Why is it every time someone mentions that they bought a game on either the PS3 or Xbox 360 that has a PC version, people tell them to go out and buy the PC version?
I realize mods can do a lot for a game, but I can't think of an instance where it really justifies re-purchasing something you've already spent 50-60 dollars on.
Sorry, just my pet peeve.
To the OP:
I think you really need to narrow down what genre you're looking for.
