I have, of course, something that can never be passed up on the PS2 and PS3: Ico and Shadow of the Colossus, as well as SMT: Nocturne (which stands as my favorite game ever). I also have inFamous and 2 (plus Festival of Blood, because Cole desperately needed the power to fly).
I used to have Demon's Souls and Skyrim, but the latter just quickly became too much of a mess to enjoy. I acquired the Journey Collector's Edition about eight hours ago, too.
I haven't even finished the OG P4 yet, I'm a bit stuck, even on normal, its a bit difficult for me cause of the enemies Defense, and attack are like WTF mainly the bosses, and Mini bosses. haha. But I'mma try to replay it on the vita. What else games do you like in the RPG genre?
