Hmm. Well, I've seen some nice ray-tracing engines for Yabasic - notably Rain_Storm's and Laurenz's - so it would be... I guess (for an experienced coder) easy to make the 3D map generated from data... and the AI could be implemented like the AI from PacMan (coded by Shocky or Xalthorn)...
I'll try and make a start - but I probably wont be able to get far (and knowing me, I'll probably abandon it in awhile!)
Any help would be great full!
