Nintendo needs to create a third brother for Mario and Luigi. It would make it easier for them to create new IP's later on. It's really easy and clever if you think about it.

A Waluigi game with mature touches would be so awesome :O

Waluigi? He is an alter ego, right? Don't tell me he already IS a third brother?
