Hey, guess what, I'm new as well! Yay!
Um... it really depends on my mood. I cycle through games. Right now I'm completely obsessed with Psychonauts. Like, writing a formal essay on Psychonauts obsessed.
RTS: Battle for Middle Earth II.
Storywise, you don't get much better than Mass Effect 2, but I preferred the gameplay in 1 myself.
And, believe it or not, the game that made the most emotional impact on me was Dragon Age: Origins. I'd have to say that no matter what, it always makes number one. I was genuinely surprised when people just said "Eh, seen it. Don't care" when the number one sellers today are FPSs that all look and play mostly the same. It's solid, I really liked the characters and I loved the theme of sacrifice that wove itself through the game...
Hm... I should write an essay on that as well...
Anyway, I guess you can tell what kind of player I am. I love Heroes of Might and Magic and just can't play Bioshock. Whatever.
And I like LotRO. Because Tolkien is my role model.
PS: I'm really surprised that a website that has some of the most intelligent gaming commentary on the web doesn't want to continue to discuss their favorite games. Huh. You'd think that everytime another post like this popped up they'd jump on it. Whatevs.
