Best first person shooter

i think Serious Sam would probably be a very a goodone to be up on that list because they didnt try to make up a lame-ass first person shooters storyline nor try to make the graphics realistic either (the graphics was still good). it was a fun game in which you get to just shoot the fuck out of everything you see and it was a good game that you can just sit back and relax on, even though its not on ps2
