but if thats not what the consumers are saying (and lets say you are right for arguments sake, sales wise) how can it be underrated?

Most of them do, and thats what the problem was.

but who determines quality? you? me? cause to me Wii's library didnt even come close to its competitors (PS36) but then you'll probably go with sales, but then with that route how can it be underrated.

So the GC isnt underrated because of forums but Wii is is underrated becasue of forums? huh?

You have to see it in the context of a stigmatized gaming community forums such as vgchartz to fully understand where I'm coming from ...

What these gamers say on forums =/= General reception in reality 

If almost all of the opinions were consistent with market responses then there would be no such thing "overrated" or "underrated" in the first place.

Aren't we talking about underrated among "core gamers" (i.e people who post in forums)? or are we talking about mainstream public generally speaking? If it's the latter then the Gamecube isn't underrated neither because most probably people don't even remember it XD, if we're talking about how the Gamecube was received among mainstream back when it released and some years later, then we can say it's underrated.

It's not a problem if you read reviews beforehand so you know what you're getting into, and only play what sounds relevant to your interests. How is that any different than any game on every console ever?

Most of the good third party games made for the hardcore gamer crowd let you forego motion controls entirely, and many even gave you the option to play with a Classic Controller. There are a few that required motion input, like Okami, Zak & Wiki, and Red Steel 2, but if you have a problem with motion controls in games like those, that's a "you" problem, and I question why you ever bothered to own a Wii at all. Okami was truly enhanced by motion controls and turned combat from a button masher into a timing and rhythmic brawler, and painting actions more seamless and natural. If you take the motion controls out of Red Steel 2, you have no game.

There was a lot of crap that was born from motion controls, but anyone who thinks it never enhanced any games is only kidding themselves.

By the way, when I say "you," I don't mean at oniyide, I mean "you" in general.

by the public Gamecube, by gamers NES!
NES is THE console, the one that change it all!

Clearly Gamecube. It was the more powerful one of the three at the time, it brought the Nintendo charm and the 3rd party grit, nice selection of games, 4 bloody controller ports!!!!!!

And it could take a higher beating compared to the others as shown on X-Play.

The GameCube had many awesome games, but it got fucked over by dumb decisions and by PS2 domination.
