Amiga Air Combat Emulator. Back in the days i enjoyed playing ACE on my Commodore Plus/4. Besides Bomber Fighter for the Amiga there are not that much "realistic" 3D Combat Flight Simulations.
It's quite a challenge to create something like this for a stock A500 (without turbo cards) - just about the right amount of fun for me to do it!
Here's a video link to the Plus/4 ACE: https://www.youtube.com/watch?v=sxeKsKWOwCk
