These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Awesome Music: The game has kickass soundtrack, especially the first game's BGM of Burn and Sonia. The opening song for the PlayStation ports are also done by Hironobu Kageyama, one of JAM Project's founding members.
Gudeath is a gravity-controllingSocial DarwinistBlood Knight whose only reason for joining Wong is because he likes murdering people, taking joy in destroying his victims' loved ones and prolonging their agony as much as possible, and being part of the Army gives him the chance to do that without consequences.
Cult Classic: While not commercially successful at the time of its initial release, the series did manage to gain a strong cult fanbase.
Ensemble Darkhorse: Shiori. Although she's seen as the Damsel in Distress from within Genshin's story in Psychic Force 2012, it's highly implied that she was gonna take a much active role in the storyline after Genshin's death had the series continued. Aside from that, there's plenty of fan art of Shiori throughout the Internet, showing that she has plenty of fans who wants to see her as a playable character from within the next Psychic Force game.
Evil Is Sexy: Subverted. The Ms. Fanservice in the series (Sonia and Regina) are aligned to NOA, who are one of the main villain factions. However, they're not as bad as Wong's Army, which lacks females on top of being utterly evil.
Even Better Sequel: Psychic Force 2012 has a bigger roster of characters, further fleshed out the mechanics of the first game and introduced some new ones while being a balanced fighting game. When it came to the home ports' localization, Acclaim pretty much learned their lesson and spared everybody from the laughably bad English dubbing of the first game and stuck to the Japanese voices with subtitles instead.
Polished Port: Psychic Force 2, the PlayStation version of Psychic Force 2012, did suffer from a visual downgrade compared to the Dreamcast version, but it does have much more features and game modes to play around with, including a Psy-Expand mode where you can level-up the characters and give them custom movesets by using moves from the other characters. Psychic Force 2 even brings back Sonia, Brad, and Genma from the first game.
Foe Yay / Ho Yay: Burn spends 2010 obsessing about Keith; Keith spends 2012 sighing about Burn. In their endings they go all in for crying out each other's names and touchingly dying in each other's arms, the OVA has Keith turning dewy eyes to the camera and saying Burn's name breathlessly as the very first scene... It's no wonder they're one of the easier pairings to find doujinshi for (although Brad/Wong is surprisingly common, too).
Rooting for the Empire: NOA gets a good proportion of fan-love and sympathy. Not really surprising for the faction analogous to Magneto, plus all of NOA's loyal members are sympathetic characters to some degree, and it doesn't help that Anti-NOA doesn't seem to have a competing plan to improve Psychiccers' lot. The OVA in particular leaves Burn looking Lawful Stupid and Keith lounging comfortably in Straw Man Has A Point territory. Having the ladies to beMs. Fanservice (and still sympathetic) also helps a lot, not to mention that Wong's Army proved to be even more evil and unsympathetic than they are.
So Bad, It's Good: If the English voice-overs doesn't make you want to rip your ears out, you'll probably get a good laugh or two from how bad some of the characters' voices sound.
Stoic Woobie: Gates. Despite being severely injured and losing both his wife and daughter after a Psychiccer attack, Gates was determined to get his revenge and turned himself into a cyborg in order to fulfill his personal mission of vengeance.
Viewer Gender Confusion: And again, no one blames you when you thought Emilio was a hot girl. Unless you got the US version, and got to hear his... ugh... very horrible... voice...
