old school....
I'm glad someone brought up "Out of this World." Revolutionary game, way ahead of it's time. I think I cried when I beat it.
We all remember choplifter, does anyone else remember the choplifter clone that game out years later... christ, I can't think of the name. Real simple resource management, to win you had to plow an a van past the enemy base. I believe the game was networkable... I know it was addictive.
The old Casady and Greene games were phenomenal, none was better than Crystal Quest. The orgasmic sigh when you beat the levels cracks me up to this day.
Best IIgs game ever: Wings of Fury.
