Doom / Doom II Greatest Game of all Time
Shadow Warrior and Blood These 2 games are so good that they were BANNED in most States and parts of the world.
Huh, I don't remember those games being banned. I know I played them back when they were out. I do remember one game that was removed from many store shelves though: Postal. The game box even had bullet holes all over it (yep, holes right through the box). The whole purpose was simply to walk around a city killing as many people as you could.
I think now that games like Vice City have gotten popular though it will be a long time before anything gets banned like that.
Another side note... obviously I don't intend on criticizing your like of the Doom series, but I think the best game of all time has to be Diablo II. I don't even want to imagine the amount of my life I lost to that game! :-P
