I'm going to agree with Steve on that. Turrican II was easily the best arcade game ever developed for the Amiga and game-wise, certainly one of the platform's finest hours, full stop.
Incredible graphics, amazing music and perfectly balanced game-play which never punished you unfairly. And, incredibly, all crammed onto a single 880k floppy which ran inside 512k of RAM. Those Germans sure know how to code...
To this day I still boot the game up from time to time and play through to completion.
Going head to head with Turrican II though has to be the Secret of Monkey Island. Great humour, brilliant characters, wonderful atmosphere and above all, heart - something missing from many of the cold, clinical games on release today.
They just don't make them like that any more. Why, I can remember when this website was all fields...(fade to rant)
