I've played tonnes as a kid.  Let's see what I remember:
- Commander Keen 1, 4, 6
- Doom (played the full version later)
- Duke Nukem 1
- Duke 3D
- Wolf 3D
- Blake Stone
- Fury3D
- Pickle Wars
- Jazz Jack Rabbit
- Raptor
- Rescue Rover
- Age of Empires
- Red Alert
- Hocus Pocus
- Some games on Mac which I have no recollection of the names (I recall one called <something> Cafe - the game's somewhat like the ice hockey table game, except the "goal" takes the full width of the table (rather than a small slot) and some opponents have psychic powers)

Have played a lot more, but really can't remember them now :/
