I like old school games because almost every one of them has tons and tons of little secrets. Like Duke Nukem 3D. You can activate a toilet and a wall opens. You can blow open a wall to get a jetpack. These games had simple controls and basically one objective...kill stuff and get to the exit.
My theory is (and I may have stated it before ... its been awhile since I posted in this thread) that the early 3D games (Doom, Duke Nukem, etc) were really just extensions of the 2D platform shooters that proceeded them. They are not much more than Space Invaders and Duck Hunt turned 3D (in principle) with their own unique twists. These types of games were created for FUN! Keeping it simple was a way of life.
