Hey great comments.
I was more thinking along the lines of writing a 3D game. Maybe an updated version of Castle Master or Legends of Valour for the AGA Amiga's. That would be pretty sweet. The Amiga is certainly very capable of texture mapping. You only have to look at games like Gloom Deluxe and the amazing looking Breathless. Even Legends of Valour had a bit of texture mapping and that was an Amiga 500 game. I'll probably start with a 2D game though.
