I have played Doom, Doom2, Duke Nukem, Quake, Quake2, Blood, Hexen,
Heretic, and Wolfenstien 3D. My favorite is by far Doom2, so if you
are saying "Why did he make a page on Doom2 out of all the games there are"
it's because Doom2 has outlive far more games than any other game in history.
Don't believe me? Do the research. Wolfenstien was a hit for 3 or 4 years,
Quake has been for a 1 1/2 years, Duke for 2 or 3, but Doom2 for 6 years
(Though probibly more, I didn't check the date).
