I don't really think you have to consider this particular problem when choosing what kind of license to use. The rules for all serious tournaments prohibit derivative works anyway, so there is no big need for a clause about this in the license. >I'd be interested in hearing what licenses other open source engines >are using and any issues that may have arisen, or if you wish you >had distributed it differently. I am using the GPL, and haven't seen any problems. My experiences with open source are 100% positive, and I happy that I decided to release the source code. My program is probably stronger than most open source engines, but still nobody has tried to clone it. Tord
