Quake was the first proper FPS to have a fully 3D polygon rendering engine and 16 bit color for dynamic lighting. The theme of the game was also very dark and that could range from moody to strange. While the level design is advanced technically, the themes are just repetitive although the action is frantic. This game also featured a title song by Trent Reznor. On higher difficulty levels, Quake was always fun to play and along with the loads of user maps and addons released for it, had a pretty long life. Quake also offered a 16 player deathmatch capability and quickly became the most popular multiplayer game in the world, during its time.
