I know some people want the addition of "create-your-own-fighter". Like in wrestling games. I personally think this is a bad idea, for a fighting game... preferably mortal kombat. Instead of this.... I think in MK7 they should have the addition of "create your own alternate costume." If you don't like someone's outfit... then you could create your own style for him/her. Kind of like a car game (where you can change the spoiler, rims, paint, headlights, etc). In certain matches you could win to unlock a... "head band" or something.

The only problem with this tho... is people can easily fake another character saying "so-so is in this game and I have a pic!" And the costume can not even fit the character at all.

People could also work on making retro costumes, if the MK team didn't have them... and post them onto the net.
