Just went to a mates house to play some Super Smash Brothers Brawl. Having played the original on N64, I was looking forward to a whole night of fun. By 10:30 PM, we were bored. The characters felt unwieldy and shallow and he maps were annoying more than interesting. If that is the best that Wii has to offer (and I'm pretty sure it is), it is a failure of a console.
You might as well have said, "having played Gran Turismo on PS1, I was looking forward to a whole night of fun playing Gran Turismo 5 Prologue... PS3 is a failure."
Basing your opinion of an entire console from playing a few hours of a single game is ridiculous.
