First of all, hi everybody! I've been lurking for a while now, but I decided to register now that I have something to ask.
I've come to the conclusion that DRM is bs, and shouldn't be used since it doesn't prevent piracy in the long run, and is just a bother for legit users. Now I think I should use some open source license, so people could mod my game if they wanted, and continue it's development if I abandon the project. I don't want to have a direct download link to the source for everyone, but I could, for example, include it with the actual game, so people would buy the game, and then get access to the source.
So, what would be a license that allows this but doesn't allow the user sharing the code to the public? Mods, of course could be distributed, but only the .class files the mod maker changed, not the whole game.
Sorry if that explanation was hard to understand, but tbh, I don't know what I'm looking for exactly either.
