One of my favorite underrated games of all time would have to be Gods Eater Burst on the Playstation Portable. This game was fantastic! Good gameplay, good voice-acting, lots of customization, an entertaining yet somewhat predictable story, etc. Well, not only did they remake it and add a bunch of stuff to it, they are also coming out with a sequel in a few months over here in America! I have yet to play the remake yet, though I plan to get it by the end of the week.
God Eater was a game unlike few others. The world was ravaged by war with evolutionary beings who had killed most of the populace. You were one of the few remaining humans and it was up to you fight for what little you had left. Working with Fenrir, you don a God Arc and face the monsters in wide-open cities while utilizing various attacks. It’s fun, entertaining, and very enjoyable. I look forward to getting back into the series when I have the chance!
