Populous - I played that HEAPS.
Flight of the Intruder - lived and breathed that for a while too.
Magic Pockets - I think I'm the only one who thought it was fun.
Barbarian 2 - my first Amy game so, not knowing any better, I loved it.
Stunt Car Racer and Microprose F1 GP - Geoff Crammond is a genius.
...but the only game that kept me coming back over and over again, to this day is...
Llamatron!
