I'd have to say that IMHO the best amiga game ever (and we're including Stunt Car, Superfrog and Hunter in this argument) has got to be 'Wings'
Not 'Wings of Fury' by Borderbund but 'Wings', by Cinemaware.
They're supposed to be working on a revamped version of this game but I've not heard anything about it.
Even now I can load it up and play for hours, there's just enough variation in it to keep you occupied and the graphics are still good enough not to make you cringe.
Play it on a reasonably quick Amiga and you're laughing.
Anyone who disagrees obviously hasn't played it. So there.
:-P
