Legend of Dragoon. The first game was good (not great), but I want it just as a personal vendetta against Sony for their tendency to screw over smaller developers by incubating them with Santa Monica and immediately dropping support. (Starhawk, Twisted Metal 2012, most notably PSAS - where Dart was cancelled as a character because Sony wanted to put two advertisement characters first and interest died because of it - the older Fat Princess games, I think even Warhawk, Heavenly Sword 2, and possibly even LoD2 which was in development around that time).
I love Sony but it's hard to respect them for moves like that, and LoD2 is the closest to a concession we'll get unless they actually have the stones to release a PSAS2.
You should check out my YouTube channel, The Golden Bolt! I review all types of video games, both classic and modern, and I also give short flyover reviews of the free games each month on PlayStation Plus to tell you if they're worth downloading. After all, the games may be free, but your time is valuable!
