I don't care a crap about online. Online is fun, but to me a good 1-player game is awsome.
People obbsess over online games and I don't see why. Really, I'm not getting Brawl because of the online, I am getting it because I've seen videos of it, and it seems fun. Super Mario Galaxy just looks incredible. I can't wait for the game. Super Mario Galaxy will be really fun, and I can see myself playing it all day. My favorite game is Paper Mario: The Thousand Year Door, and that's a 1-player game. Really the only reason people get Halo is because of all the violence and the online. I don't see why people think Violent games are fun. That's the reason GTA is so popular, it's all about violence. I like all the Mario games, and they don't have to be very violent to be good.
Anyway, I'm getting off topic.
I might get Metroid Prime 3, and I agree that it's not getting enough attention. Same with Super Mario Galaxy. All the hype is on Super Smash Bros. Brawl. Why? because it has online. Super Mario Galaxy and Metroid Prime 3 need more attention
