I think it would be a blast to include achievements, if you guys don't want to do it as well than at I could have it at least in a challenge thread of my own where people can fight me for fun and achievements. Some of them you'd have to figure out how to unlock. As an easy example, "Kill Two Birds With One Stone" achievement would be unlocked by choosing to fight two of my characters at once who are birds/have bird-like qualities and kill them with a single stone (only the finishing blows need to be done with the stone). There would be a mix of humorous ones like that and serious ones that offer greater challenges such as making your opponent more powerful than normal.
