The old PlayStation game Apocalypse is frequently boasted as one of the first games to use mo-cap technology, with Bruce Willis voicing and performing motion-capture for the game's hero, Trey Kincaid. Unsurprisingly, this makes Trey appear exactly like Willis during the 3D cutscenes.
Beyond: Two Souls entire cast (including Elliot Page) falls under this category, since they have provided the voice, likeness, and full motion-capture performance for their roles.
BioWare has been doing this a lot in their games since they started using modern game engines:
Yvonne Strahovski's character in Mass Effect 2, Miranda Lawson, is basically her with, um, larger assets. Originally, Miranda was even a blonde, like her actress, but the team felt the character worked better with black hair.
The Illusive Man from the same series looks remarkably similar to Martin Sheen, only a bit younger.
Mass Effect 3 also adds in Jessica Chobot, a real-life journalist playing fictional journalist Diana Allers, with her actual likeness, and Keith David as Admiral Anderson. The humanoid version of EDI also bears more than a passing resemblance, physically, to voice actress Tricia Helfer.
An unintentional example is Bastila Shan from Knights of the Old Republic. When developers realised her official artwork greatly resembled Jennifer Hale, they decided to run with the idea and redesign the character to include these similarities.
Slaps and Beans is a game that pays homage to the many onscreen collaborations between Terence Hill and Bud Spencer, where the player are in control of digitized sprites resembling those two actors, right down to Bud's mustache.
Several of the characters are modeled after their voice actors, most notably Sam Witwer as Galen Marek (when he joined Smallville it can be a bit surprising), Nathalie Cox as Juno Eclipse, and Cully Fredrickson as Rahm Kota, as well as Adrienne Wilkinson as Maris Blood. As with the above example, it works rather nicely.
The use of motion capture to better animate the characters' faces (by capturing the facial expressions of the voice actors) was a huge factor in this.
Ink Suit Acting in LucasArts games goes all the way back to Dark Forces 2: Jedi Knight with the main characters rendered in the likeness of the actors who portrayed them in the live action cutscenes. Jason Court hasn't been Kyle Katarn's voice actor for everything, but his appearance has continued on through several additional games. On a different note, the Star Wars Customizable Card Game's portraits for Talon Karrde and Corran Horn depicted their creators (Timothy Zahn and Michael J. Stackpole) in costume as their characters.
Brütal Legend: Eddie Riggs in was deliberately designed to look a bit like Jack Black, even before it was a done deal that Black was playing him. There's also Ozzy Osbourne as the Guardian of Metal, Lemmy as the Kill Master, Rob Halford as The Fire Baron, Brian Posehn as the Hunter, and Kyle Gass as the neurotic cannoneer.
Dead Space's major characters are modeled after their voice actors. Peter Mensah does Hammond, Tonantzin Carmelo does Kendra, Navid Negahban does Mercer, Keith Szarabajka does Kyne and Iyari Limon does Nicole. The biggest exception was Isaac Clarke in the original, who had no dialogue (beyond screaming and grunting) and whose face was only shown at the end. When he started talking and showing his face more in 2, they changed his model to look much closer to his voice actor, Gunner Wright; and as they recast Nicole, they changed her model to match her new actress, Tanya Clarke.
Most characters in the first few games of Assassin's Creed are modelled after their voice actors.
This is especially noticeable for Assassin's Creed II, because said actors also played their game role in the live action series of short films Assassin's Creed: Lineage, released as companion piece for the game.
In Halo 5: Guardians, the members of Fireteam Osiris are all modeled to look like their voice actors, with one exception; Jameson Locke was modeled after his original voice actor Mike Colter (who had already portrayed him in the live-action series Halo: Nightfall), but they had to switch his voice actor to Ike Amadi due to scheduling conflicts with the Marvel Netflix shows Jessica Jones (2015) and Luke Cage (2016).
In Halo Wars 2, Captain Cutter and Professor Anders have been redesigned to look like their new voice actors Gideon Emery and Faye Kingslee.
SpyHunter: Nowhere to Run had Dwayne Johnson, AKA The Rock, provide his voicework and likeness to main character, Alex Decker.
Many of the "talking heads" in Fallout bear at least some resemblance to their voice actors.
Bit earlier: Gackt played AS Genesis in the extra ending scene to Final Fantasy VII: Dirge of Cerberus after collecting all the G-Files/G-Reports.
All over the place in Battlefield 3; Agent Gordon is clearly Glenn Morshower, Blackburn is Gideon Emory with shorter hair, Vladimir is Ilia Volok with extra scars...a weird case, though, is Dima, who is modeled after Oleg Taktarov, but voiced by Andre Sogliuzzo.
Heavy Rain: The four main characters basically look like their voice/mocap actors. Especially Scott Shelby looks exactly the same as the actor who plays him.
All three games in the Onimusha trilogy each featured a protagonist modeled after an actor: the first game stars Takeshi Kaneshiro as Samanosuke, while Jubei Yagyu in the second game was based on the late Yusaku Matsuda. Samanosuke returned for the third game, where he is joined by french soldier Jacques Blanc, based off none other than Jean Reno, who also did the French dialogue at the start of the game before Translator Microbes forces him to speak with another voice. This reliance on the use on actors likenesses is part of the reason why Capcom took so long to re-release the series on modern consoles and even then, they only got the rights to re-release the first Onimusha.
For the remake of GoldenEye (Wii), in addition to Daniel Craig lending his likeness to James Bond, Alec, Xenia, and Natalya are modeled after their voice actors.
Granblue Fantasy: Nobuo Uematsu appears as "Nobiyo", one of the most famous composers in the sky and basically is just Uematsu in the Granblue art style, and he also does the voicework.
In Grand Theft Auto: Vice City, Cuban gang leader Umberto Robina, Colombian drug lord Ricardo Diaz, and corrupt Texan land developer Avery Carrington resemble their voice actors Danny Trejo, Luis Guzman, and Burt Reynolds respectively. Trejo and Guzman also reprise their respective roles in the prequel Vice City Stories.
In Grand Theft Auto: San Andreas quite a few of the characters are modeled off of their voice actors, including James Woods as MIB Mike Toreno, David Cross as Zero, Charlie Murphy as Jizzy B, and, perhaps most notably, Samuel L. Jackson as OfficerFrank Tenpenny who also shares some of the mannerisms Jackson typically has in his other films. The Grove Street gang, meanwhile, is mostly modeled after the members of N.W.A.: CJ is Dr. Dre, Ryder is Eazy E, and Sweet is Ice Cube.
Phil Collins is the first celebrity to appear As Himself in the GTA series in Vice City Stories. There is even a mission involving him where the player must prevent the Forelli mob from sabotaging Phil's concert.
In Grand Theft Auto IV, Ricky Gervais and Katt Williams appear as themselves for the Split Sides Comedy Club routines (with Frankie Boyle added for the Lost and the Damned DLC) while former UFC fighter Bas Rutten appears as a hyper-masculine parody of himself in The Men's Room in-game TV show.
Vin Diesel does this frequently. Wheelman, for instance, was labelled "Vin Diesel: Wheelman", as a pile of polygons arranged in a not-un-Vin-like shape 'played' Milo Burik, an undercover CIA agent.
In Metal Gear Solid 2: Sons of Liberty, Hideo Kojima apparently found Akio Ōtsuka's offscreen personality charismatic and interesting enough that he instructed Solid Snake's motion capture actor to copy Ohtsuka's mannerisms and the way he carried himself. Details like the particular way Snake holds his cigarettes are based on Ohtsuka.
Quiet in Metal Gear Solid V: The Phantom Pain retains the likeness of her motion/voice actress Stefani Joosten, along with Ocelot sharing his features with Troy Baker, and Huey resembling his voice actor Christopher Randolph.
L.A. Noire used Motion Capture technology, developed specifically for the game, to fully capture the actors' facial expression. Recognizable actors among the cast include Aaron Staton of Mad Men and John Noble of Fringe.
Call of Duty 4 has Staff Sergeant Griggs, who was voiced by, named, and modeled after Infinity Ward's lead animator at the time, Mark Grigsby.
Continued in Call of Duty: Black Ops: excluding the "named after" part, it's the same as above for Alex Mason (Sam Worthington), Jason Hudson (Ed Harris), and Joseph Bowman (Ice Cube).
Devil May Cry 3: Dante's Awakening: The game's cutscenes were filmed using motion capture, and if you find the behind-the-scenes videos of the recording sessions, you'll notice that the voice actors (particularly Reuben Langdon for Dante) look very much like their assigned characters.
Devil May Cry 4: According to Lead Motion Manager Hiroyuki Nara in page 216 of the 3142 Graphic Arts artbook, Agnus's voice actor, T.J. Storm, "looked just like him".
Star Trek Online has appearances by (usually aged-up) versions of several characters from the live-action Star Trek series, with the original Trek actors voicing the characters. The game started out with Leonard Nimoy as Spock, and so far has added Denise Crosby playing Empress Sela and a once-again-time-shifted Natasha Yar, Michael Dorn playing Ambassador Worf, son of Mogh, and as of Season 10, nearly the entire cast of Star Trek: Voyager (as well as a few supporting characters) save for Janeway and Chakotay. Also, Captain Va'Kel Shon, CO of the Enterprise-F, is the spitting image of his voice actor Dave Rivas, except Andorian and clean-shaven instead of human with a goatee.
Need For Speed: The Run features accurate CGI representations of Sean Faris and Christina Hendricks, the latter even depicted accurately with regards to her, um, proportions.
Red Dead Redemption II: Arthur (Roger Clark), Dutch (Benjamin Byron Davis), Bill (Steve J. Palmer), Hosea (Curzon Dobell), Jack (Ted Sutherland), Leopold (Howard Pinhasik), Sadie (Alex McKenna), Susan (Kaili Vernoff), Tilly (Meeya Davis-Glover), Micah (Peter Blomquist), and Swanson (Sean Haberle) greatly resemble their real-life voice actors.
Rise To Honor: Jet Li provided his voice, likeness, and motion capture performance for this 2004 Playstation 2 game.
In Horizon Zero Dawn, the character Sylens looks exactly like his voice actor, Lance Reddick, but with a few extra tech additions to his face and body.
James Sunderland, the main character of Silent Hill 2 was modeled after his voice and mocap actor Guy Cihi.
Claudia Wolf in Silent Hill 3 looks like an older albino version of voice actress Donna Burke, who also voiced and was the design basis for Angela Orosco in the previous game.
Henry Townshend and Eileen Galvin from Silent Hill 4: The Room are modeled after VA's Eric Bossick and Anna Kunnecke, respectively.
The Like a Dragon series is well-known for featuring the likenesses of its voice actors rendered realistically. Many of those actors include veterans of Japanese gangster films, such as Takeshi Kitano and Riki Takeuchi, as well as famous AV actresses portraying hostesses. Like a Dragon: Infinite Wealth, with its Hawaiian setting, extended the practice to American film stars such as Danny Trejo and internet personalities such as Kson On Air.
Fallout 4's characters who are modeled after their VA's include the Vault-Tec Rep (Paul Eiding), Nick Valentine (Stephen Russell), Preston Garvey (Jon Gentry), Mama Murphy (Maya Massar), Piper Wright (Courtney Ford), Travis Miles (Brendan Hunt), Magnolia (Lynda Carter), Desdemona (Claudia Christian), Deacon (Ryan Alosio), Glory (Chelsea Tavares), Tinker Tom (Byron Marc Newsome), Paladin Danse (Peter Jessop), Lancer Captain Kells (Tim Russ), Scribe Haylen (Jan Johns), Conrad Kellogg (Keythe Farley), Unmutated Brian Vergil (Matthew Waterson), Synth Shaun (Aidan Sussman), Father (Tony Amendola), MacCready (Matthew Mercer), Liam Binet (Fineas O'Connell), Rex Goodman (Richard Tatum), Swanson (Christopher Salazar), Honest Dan (Jonathan Roumie), Gwen McNamara (Cindy Robinson), Bobby de Luca (Brandon Bales), Cait (Katy Townsend), and Irma (Elisabeth Noone).
Played with by the Terminator, RoboCop, and Rambo. Their appearances (or at least, the Terminator's human tissue coating's appearance) are based on Arnold Schwarzenegger, Peter Weller, and Sylvester Stallone, respectively, but the Terminator is voiced by Chris Cox instead of Arnie himself (though he gave his blessing for his likeness and picked Cox), and while Weller and Stallone returned to respectively voice RoboCop and Rambo, the characters are based on how the actors looked in the respective franchises' prime, not as they looked at the time of recording, leading to Vocal Dissonance where the old actors voice their younger characters.
Ghost of Tsushima main cast are all modeled after their English voice actors.
Cyberpunk 2077: Keanu Reeves provides likeness to the Deuteragonist, Johnny Silverhand. He also provided motion capture and speaking lines (but not the singing voice).
The entire main cast of Death Stranding is made of scans of the characters' actors (including Léa Seydoux), who also provided voices and motion capture. The only outliers would be Deadman (likeness of Guillermo del Toro, played by Jesse Corti) and Heartman (likeness of Nicolas Winding Refn, voice of Darren Jacobs). Many cameos are also scans of different people, but they're usually voiced by prolific industry voice actors.
In Haven (2020), Yu (Janine Harouni), Kay (Chris Lew Kum Hoi), Erena (Jane Perry), and Ozias (Harrison Collett) are all designed after their voice actors.
Stray is an unusual case. The meows and cat sounds in the game? An actual ginger cat named Lala, who is the spitting image of the adorable in-game moggie.
Augustus Cole looks exactly like his voice actor, Lester Speight. Which is the whole point, since the entire idea behind the character was to pretty much just take Terry Tate, Office Linebacker and put him in a video game, which included getting the same guy to play him.
Aaron Griffin looks like Ice-T. Again, this is the whole point, since Ice-T is a fan of the series and (perhaps half-jokingly) asked to be put in the game. He probably wasn't actually expecting them to say yes.
Starting with the 2010 Alan Wake, most characters in Remedy Entertainment games are directly modeled off of their actors. This makes it much easier for them to play with Medium Blending, and having those actors portray their characters in Live Action Cutscenes.
