Not sure if this is a dumb idea or not...
I was thinking maybe it would be a good idea for them to make a less violent version for the younger fanbase. For instance, the Wii version wouldnt have any blood or fatalities and the 360 and PS3 version would, and they would have the Mature esrb rating as well. I think it might be a way to put all the hardcore MK fans' complaints at ease. Also, DC doesnt have to worry about the younger fanbase witnessing batman's spine being ripped out of his body. The only problem i could see with the idea is complaints from the older fans that have a Wii, and would like to have the version with all the violence. But I doubt they would be able to release two version for each console.
I dunno...its an idea....
