Some of these choices are just so unrealistic it's not funny. I thought this was going to be a half-serious thread. :P
I remember seeing Pirates! Gold on PC, and I always hoped they'd release the Deluxe versions on the Amiga 1200. Only Civilization ever got a "deluxe" version, but I can't even begin to comprehend how great Pirates! Gold would've been on the A1200.
No, the CD32 version doesn't count... that was basically a port of a Megadrive game.
