The creator named Warhammer has their games starting off with a disclaimer that their game is not-for-profit to cover themselves. They even had someone else upload their game and try to sell it. Fans saw this and notified Warhammer so they could stop it. Be careful.
All my projects so far have been non monetary not even donations are active (money I could certainly use). Never heard of Konami targeting non monetary fan games. They have always let fans be fans, atleast so far. But if they said I need to take this down I would take this down. Then I would use what I had done in engine and graphics and make a new game thats not a fan game. I would how ever put a small price to that game (3-5 dollars). I do have some cool plans for making a new metroidvania like game that more RPG and more darksouls like. Even now I have 2 commercial projects coming (dungeon crawler and a rogue like) but my main focus (90%+) is on this game. Once this is done then the focus shifts.
I'll look for those games you're planning!
Want to ask something - I'd like to do a logo for my gaming channel that looks like the CastleVania 2 logo, but says "J.Q. Belmont's Gaming and Adventure Channel". Like have the "J.Q. Belmont's" part in the long pointy bar and the "Gaming and Adventures Channel" part below it. I would pay to have someone do up a PDF of that. If that's not possible, I totally understand.
