I am building a game using the Super Tux assets. It is NOT an asset flip, game has a totally different main concept, new mechanics, 4 new boss fights, built with a different engine.
When I first started building the game, it was supposed to be a FOSS game. But after spending a ton of sleepless nights working on it, I would like to get compensated.
Donations will probably not cut it, judging by what most FOSS games go through. I’m a huge fan of FOSS, so it does feel wrong releasing a commercial games where 80% of the assets are from volunteer work.
On the other hand, the license approves of this. If they have an issue with it, they would have chosen another license, correct?
What do you think?


A few others have mentioned the same, but I agree it seems you are conflating a game being FOSS with it needing to be free.
I make FOSS games with my wife, because I believe in the rights it grants the player/user of the software.
The code and assets are available to those it matters to, but for the vast majority of people who just want to play the game, they can buy a precompiled build on Steam or Itch.io, allowing us to get some support to. (Though in our case, our short coming is marketing leaving us stuck at 9 reviews and barely any sales regardless)
But strictly to your question if for some reason you still don’t want to open source your work, yes as long as you follow the license with reasonable attribution and such I don’t see an issue with it, that’s why things are open sourced and not given a NC/non-commercial license.
