I never stated anything about licenses for p32c, but i uploaded the sources some time ago (without announcing it too much), so what license would that be?
Hidden open source?...
This is the definition of freeware I've found
Software classified as freeware is normally fully functional for an unlimited time with no cost, monetary or otherwise. Freeware can be proprietary software available at zero price. The author usually restricts one or more rights to copy, distribute, and make derivative works of the software. The software license may impose restrictions on the type of use including personal use, individual use, non-profit use, non-commercial use, academic use, commercial use or any combination of these. For instance, the license may be "free for personal, non-commercial use".
As far as I've read, you're worried about a possible abuse, right? Anyway, why don't you try a less restrictive license that states explicitly you must mention the original author and you can't claim the copyright of derivative works, like let's say Creative Commons (just an example
)? Actually, the sources of pak96.comic are not available yet, are they? thus does it have sense to use a restrictive license if the sources aren't public?
PS: You could also do the same as Simutrans, that uses Artistic License but extends it in some aspects like avoiding commercial use of the game for third parties.
PS2: although It may seem so, I'm not trying to force you to take a decission or to change anything. It's just another annoying discussion about licenses...
