@ JoannaK:
As you will know, "BlitzMax" (based on OpenGL) is still a looooong way off. Don't even think about it for now, Joanna. Also, there is a new release called BlitzPlus which is aimed towards more serious programmers but was designed specificially to use the Window GUI (native windows, etc.). Porting BlitzPlus wouldn't be easy either even though it lacks all the cool 3D features.
Please note that the basic idea to have something like Blitz3D running on MorphOS, is most certainly an exciting one. This could increase the quantity of released software by quite a bit. I just feel that the PC version of Blitz is probably not an option at this point in time. Perhaps we should rather concentrate to support efforts such as PowerD or a MorphOS port of AmiBlitz2000 (Open Source variant of the former BlitzBasic for Amiga).
