To start:
@ Whknight: I never played the game for the first few months, so I can't really tell if it changed much. But for the PC, I find the game is very well designed, almost no clipping issues or game map flaws that can be exploited. Some annoying bottlencks (Operation Metro...) and some annoying guns (USAS12), but besides that the game is pretty balanced.
