Again - Licensing for MOS or AROS would then raise the cost for a licence.

Currently biggest Amiga market for games (even in the various small sub-markets) is AmigaOS 3.x 68k. So if doing anything which makes sense it would need to be a licence for AmigaOS. Adding in MorphOS and AROS would triple the licence price. You won't get a licence for "something which is mostly source-code compatible to AmigaOS".

And at least as to MOS you can get it supported with a WarpOS version which still would be a "AmigaOS 3.x version" so covered by a licence for AmigaOS.

I think both OS4 and MOS don't have much more option than the other (MOS the better Browser and thanks to Mac machines better availability, OS4 the better 3D Solution) but in the end it is a personal decision which you like more.

Both markets - at least as to commercial game porting - cannot pay a licence on their own (68k MIGHT but not sure, it is better that with OS4 and WarpOS versions you can get the game to WarpOS machines, OS4 machines and MOS machines as well, OS4/WOS versions basically "riding" on top of 68k - I was not aware of this till recently myselves - I always thought OS4 would be the biggest ^^).

Licencing for MOS-only is not financially viable (at least not anymore, probably was in the past) and also it would mean me developing for a system which I do not even own (my fav "Amiga-kind" is OS4, but as you will have seen recently I also support other platforms which can be covered with "AmigaOS licence").

My current plan is still for future games to support 68k/OS4/WOS in parallel. And I have some Betatesters who have MOS too, so they can test the WOS-Versions on MOS (one of them several different MOS-systems).

If you want to continue to discuss this I suggest not in this thread but open a separate thread on this forum.
