It's more like the creator could actually make money off of non-fan content. The Wind's Disciple is an excellent example of a full game that is sadly limited by being fan stuff. If the premise of a game CAN be detached from a fan setting, it should. If not, that's fine.
I have some original ideas lined up after I finish this game. This one is more like a passion project so even if it don't make money it's okay. My main objective is to improve my skills and have some fun in the process. But I do undestand your point.
this was actually a compliment that they are so good they can do things that are better than fan games xd don't search for haters where there are none xd
