The series as a whole
- Dueling Games: Friendly, with the Quake series, natch. Specially, Quake III: Arena vs. Unreal Tournament, (being the greatest FPS feud of all time, and one of the ultimate cases of Internet Backdraft in its time) and to some extent, Quake II vs. Unreal.
- Hey, It's That Sound!: If you're a fan of the Unreal games, you'll notice that there're several event/weapon/explosion/ambient sounds carried from older Unreal games. Hell, you can even hear some sounds from the first Unreal game in some stages of Unreal Tournament III.
- Promoted Fanboy: The first Unreal Tournament came to the stores with around 8 mappers having worked on it, some of them gathered from the same Unreal community. The game was a success. Also, its modding and mapping community grew very well. By the time Unreal Tournament 2004 came out, the quantity of mappers grew up to almost 20. The most played map of the game, Rankin, which also made its way onto the demos, was made by the community mapper Hourences. He also made the most played Onslaught map of the game, Torlan, also in the demos as well. Both maps were made for that game in particular. Hourences is now working on the RPG The Chronicles Of Spellborn, and has released two books called "The Hows and Whys of Level Design".
Due to this, Epic Games tried to do UT3 more "modding friendly", and the success it has is still up for debate.
- What Could Have Been: There was a cancelled project called Unreal Warfare, which became Gears of War, according to Word of God. The name was used again to refer to a new gamemode for Unreal Tournament III, which ended up being basically Onslaught's power-cores-and-nodes with Assault-style mini-objectives added.
- In a lesser note, Vehicle Capture The Flag is a standard game mode in UT2004, however as no maps shipped with the game that use the VCTF- prefix (and thus are recognised by the game as Vehicle CTF maps), the game mode is hidden. Only by downloading and installing user-made maps for the game mode can you play it. By UT3, Vehicle Capture the Flag lost it's identifying prefix, meaning some regular Capture the Flag maps would have vehicles to use, and others wouldn't.
- At one point in time there were plans to port the original Unreal to the Nintendo 64 via the Disc Drive add-on, with said port being made by a smaller division of DMA Design (now Rockstar North). The port was cancelled for two primary reasons: first the Nintendo 64 Disk Drive never left Japan, and even so was a huge flop, and secondly the division of DMA that was to handle the port went out of business just before DMA was bought out by Rockstar Games and became Rockstar North.
Trivia about the Unreal engine
- Unreal Engine 3 is one of the most licensed video game engines of all time, with it being used to power games across multiple genres. Mostly sticking to first and third-person shooters like Epic's own Bulletstorm and the Borderlands series, however other genres have been made on the Engine, including superhero brawlers, fighting games, third-person hack-and-slash-and-possibly-shoot games and turn-based games.
The TV series
- Romance on the Set: Johanna Braddy (Anna) and Freddie Stroma (Adam) became engaged in May 2016. Hopefully Life will not imitate art, since Anna didn't go through with the wedding on Everlasting.
