Silent Service (submarine game from A500 days) is one of my all-time faves. Very tough game to win as even if you manage to sink one or two ships, they launch so many depth charges and/or ack-ack at you, your sub gets sunk in short order....
Stunt Car Racer (pre-AGA game also), not as obscure but ridiculous tracks and scenario and purely entertaining....
TFX - fairly obscure as never published, save on the CU Amiga cover disks/CD in 97(?) - jet fighter game, very cool...
Was there a version of Ballblazer for Amiga? I know it was on C64.....
