Ok, Doom, Half-Life.... original? Lets go back further, Wolfenstein?
Nah...... All of these kind of games are a derivative of one game...... PacMan!
All these games are are 3D versions of PacMan, Kill the ghosts=kill the badguys/aliens, pick up a power pill=pick up extras, collect all the pills to finish the level=collect everything to finish the level.
:laugh That's really a "little" bit far-fetched, don't you agree guys?
If you want it that way, you might as well call "Evil Twin" a 3D version of ROGUE
