Every shooter that allows custom maps from the late 90s and early 00s has a map resembling Columbine. If your reason to not make a game is because someone might turn it into something horrible, there would probably be no games.

You’re right. Giving 30% for really fucking good platform services is way worse than having to find a publisher that takes in 70 to 90% of revenue and pushes devs to release unfinished games.
