Just been playing Medieval 2: Total War, and I have to say, for someone who isn't really into RTS games, I'm really, really enjoying it.
Now to go crush the French dog underfoot. They have encroached 'pon our lands more than too many times... TO ARMS!
And to the poster who mentioned Oblivion; I have Oblivion, but always found it to be lacking. In Morrowind, the game seemed to be drenched in lore, but for OB, I found that aspect lacking. It seemed to not be as deep as MW. However, that does not mean that it doesn't have standout moments. For example, the Dark Brotherhood questline, and the Shivering Isles expansion.
To the OP: It seems that you don't have a particular liking toward FPS games. however, S.T.A.L.K.E.R: Shadow of Chernobyl is a really, really good game. If you can, give it a try. When you're standing on a grassy hill in the middle of near wastland and delapidated buildings around you, rain coming down, and mutant dogs barking off in the distance, you're struck with an overwhelming sense of loneliness. But do you know what? I wouldn't have it any other way. The atmosphere is what makes the game.
