The first FPS that I actually enjoyed was Goldeneye. There may have been FPS' before 007 but I feel it was the big breakthrough with the genre. Doom was too much like a 2D dungeon game with 3D walls and sh*t AI.
Watching people talking about games (no matter how awesome the games that is spoken of might be) isn't fun. PLAYING those games is ^^
Hey guys, I have a link to some gameplay from Quake,but PM me asking for it, so it won't get seen by someone who'll take it off.
