The Wii has only been out less than a Year, has plenty of excellent games, sure there are some crap ones, but that is the case with all systems. 2008 will be a much better year, and 2009 will definitely be even better, you cant compare the Wii to the 360, they are not in competition and the 360 has been around alot longer, but then, are there any games on the 360 which are not FPS? ....
Give Wii time, it will come out on top, just like the DS.
Sony got it all wrong with PSP and PS3, they relied on power, assuming its what people want. So they basically cornered the rich stupid market, who want "the best", so the rest of us can enjoy systems like DS and Wii which offer many things no other rival does. And it works.
