“In the past, in the eighties and nineties, that was a major issue. I remember the big ‘Mario vs. Sonic’ debates. What we see today is that the influence of exclusive titles on the sales curves becomes ever smaller. In addition, we are in a situation that there is a head-to-head race on several consoles and that nobody is super clear in leadership – especially in matters of the PlayStation 3 against Xbox 360.” – Microsoft’s German Xbox 360 product manager Boris Schneider-Johne
In the case of the Wii, I believe that exclusives are important. I just don’t see the Wii in the promising position as it is today granted the 360 or PS3 also had Super Mario Galaxy, Twilight Princess, Metroid Prime 3, Zack & Wiki, Boom Blox, and countless other titles on their systems.
