I'd love to see the GRAAL and GRAC2 engines supported.

Interesting fact is that all game scripts and room descriptions are in text. All music is in .MOD and .SND, and graphics is in .IFF. All are supported by ScummVM. Thus, somebody could potentially reimplement the engine even without the sources. I knew about the graphics and music, but I didn't know...

GRAAL was a point-and-click game engine for the Amiga. Most games created with it are now freeware, the most famous one is Muscarine, which can be downloaded from both Aminet and from its official website where language packs in German and Polish are available too.
