I would definitely like to see Skullgirls characters made available(particularly Peacock), but I know that's somewhat infeasible without incredible time and effort just for the sprites alone, as I'm pretty sure all the characters are hand drawn(don't remember where I heard it from though).

That being said I also came up with an idea for an SCP Containment Breach mini game character that I lack any of the spriting skill to make but have so many ideas.
