There wasnt really much they could do...
i cant see why your all moaning about the look of the console, the xbox did better and look at the thing! I like my black Gamecube.
Yeh advertising would've helped the amount of AC adverts on tv seemed of really helped, as its still in the top 10! Seems like nintendo are on the up!
I dont think online was essential to be quite honest, the PS2's online is shabby at best, and thats a succesful console.
More franchises needed eh?!
Pikmin, metroid (well it was trasformed fantastically to 3D), battalion wars, chibi-robo, odama, Monkey ball and more.
I think their top games could've been improved. Games like Sunshine wernt very gorund-breaking, quality gaming but it lacked some magic. Same with mario kart.
But if they carry on producing games like smash bros and the like theres no wrong they can do.
