Little Big Planet, Fallout 3 and Far Cry 2 and Tales of Vesperia.
All really fun.
Fallout took me a little while to get used to, but I'm beginning to get the hang of everything. The only Action/RPGs I've ever played were System Shock 2 and Bioshock... Fallout is cool for its moral choices and such you can make. It would have been cool to give my guy a voice. I'll talk about it more when I play more.
Tales of Vesperia is awesome. Its my first Tales game, and I love it. The battle system is fun, and the main character, Yuri, actually has a good story and personality to back him up. The leveling system isn't bad, but its hard to get everyone to level up together. I guess I'll just have to shuffle up my party every so often.
Little Big Planet is a load of fun. Its cute, and looks beautiful. Not very much of a story, the main point I believe is just to get stuff to make levels. But the amount of objects and prizes surpasses even Brawl I think. Its huge. And man, Stephen Fry is a great narrator.
Far Cry 2 is pretty neat. I've kinda dropped it since I got Fallout/LPB, but its not bad. It takes a RIDICULOUS amount of time to get anywhere though, so if you want to travel, you better have a car. And you better drive off road, because if you stay on the roads, you WILL get shot at and you WILL be followed until somebody dies. But theres tons to do, and tons of way to do it, so it has a good pull to it.
