What good ORIGINAL games are on PS3?

I love my XBox because of the arcade shooters exclusive to it and it's amazing XBox Arcade library. And I love my...I hate my Wii. But I noticed something I was missing in my life. Exploration. Adventure. And dungeons. I played Oblivion and Fallout 3 (hated New Vegas, don't recommend it to me) but I need more. Nintendo has lost their charm and I can tell without a doubt I will enjoy Motion Swo- I mean Skyward Sword and Xbox has none coming out soon. At least nothing decent. I want to see whant the PS3 has got. I saw 3D Dot and said "What happened to that, Nintendo" than cried like an indian in a polluted city. What's Sony got under the hood with originality and quality? No sequels, please. I'm bored with God of War. And I played Uncharted...let's just say Noob Saibot's fatality looks more fun than that...crap if it can even match the quality of fresh excrement.
