The beauty of projects like marvel rivals is that it has the ability to elevate niche and obscure characters like luna, c&d, lin lie, and even Jeff who's essentially the face of the game. Adding an OC would be no different so long as it's done right.
This sucks, a lot.
I wanna play the heroes grew up with. There are THOUSANDS of them, from A-listers to C-listers
There is no need AT ALL to create new characters when they can just use what we already have
I wanna play Dr. Doom, Ghost rider... Not some made up dude like luna
