How can you ignore Rol's arguement? 2d Marios are among the best selling games of Nintendo's library. Releasing a system should be viewed akin to MS releasing a system without Halo or Sony releasing one without Gran Turismo. I do believe other mistakes were made with the N64 and GCN led to their poor sales that not even a 2d mario would have remedied though.
