Not at all... But what happens when you have the hardware and creativity? See, I'm not saying there can't be good Wii games that the creativity is there and fresh... It could be vastly more fun than a run of the mill graphical/physics HD capable game... But people have this misconception that only the Wii can allow creativity, which is bullshit... Yeah, maybe the hardware is going to force devs into coming up with a twist to the regular formula, but doesn't make it a sure thing either...
And I'd hate to break it to those people but, a creative Wii game < an equally creative PS3/360 game because the hardware will allow to push the entire envelope (*See Little Big Planet) as visuals and physics clearly enhance the final product... There's no denying that...
And, to say "who needs voice chat" is the prime example of Amir0x's "Jaded" comment... Yeah, stuff didn't have it years ago, then got it, but when it's not there now, it sucks... (*See CoD3 PS3)... It enhances the community aspect greatly and allows levels of coordination that can not be on games without... Oh, and makes games more fun to joke around/trash talk...
