You can’t even do a copy of it with assets made from scratch. I was making an MK game too with some friends, only using the idea of MK1, but making all the art, code and audio from scratch. After the game started coming together, I got a call from Warner Brothers, saying that I can’t share it with anybody. I said it was a fan project for free, using original content. It didn’t matter, just a close reference to the IP is enough for them to get on my case.
I thought it was alright for a while, because some of the original creators of MK, John Vogel, and John Tobias, saw the work and thought it was pretty cool. They don’t own the IP though, so it doesn’t matter what the makers of the game think, but who owns the IP.
I’m learning how to use UE4 now to make a fighting game, but it has to be something original. It sucks to be a fan of these games, and want to make your favorite characters so bad, but you have to fight the urge…
Here’s what I was making. https://www…com/user//videos
