Exactly, Robotor! EVERY Nintendo game that is simple, ALSO has an incredible amount of depth if you keep playing it. Get over this "non-gamer" bullcrap. It doesn't even make sense, DVD's are for non-gamers, Microwaves are for non-gamers, not ANY videogame.
Sure, Nintendogs would be one of the few new games to appeal to people who aren't big followers of games and don't visit message boards where everyone bitches, which is a great thing! The audience and userbase gets bigger and more varied! Gamers at Famitsu also loved the game! Everyone wins!
Anybody who calls a game too short or too easy, has no imagination whatsoever, due to being fed the bullcrap idea that's being fed to people subliminaly through crappy reviews and the internet, that you should only play what the game tells you to play, and yes, i'm sorry, but you're in the minority. In Grand Theft Auto, there are missions that are what progresses the "story" throughout the game, but guess what? The missions aren't as fun as bumming around doing whatever you feel like. Don't like old ladies? Run as many over as you can before you either get killed or get arrested by the cops, fun! Oh damn, time to do a mission.
For example, if you only spend 4 hours on Wario Ware, you're COMPLETELY MISSING THE POINT of the game. It's not to storm through as fast as you can and merely play every microgame then hop straight on the internet and complain, it's to challenge yourself and see how well you can do in your favourite microgames or minigames. Just because you've played a game before, doesn't make it totally pointless to play again because "you've already beaten it", the point is, if it's fun, keep playing it. I've played Wario Ware Touched for i'd say.. around 50 hours now, and I only just unlocked Pyoro T, I could have unlocked it really quickly if I just stormed through the game filling in the "requirements", but that's boring, i'm not going to force myself to do that, because I don't want to, and guess what? I don't have to either. It's an "and" game, Nintendo are an "and" company, don't like my approach to the game? Well that's fine, just don't bitch about why your approach to it sucks.
A game only lasts for 5 hours if you only spend 5 hours playing it. The only time I see the short and easy comment as valid, is if the game sucks and you aren't enjoying it, but then if you didn't like the game you wouldn't play it til the end in the first place.
What the text? Originally I was just going to say something simple that agreed with Robotor.. now.. I don't know WHAT i've said, i'm tired. (epic non-gimmick hardcore post?)
