Mario & Sonic can be honored for variety and fun, but just not for size.
The things that make this game most disapointing are probably the amount. There is not much packed in this game. You could fit it in a 1/3 layer disc probably. The lack of characters makes this considered as crap. Where is Donkey Kong? That's just one of the players missing. Also missing is lots of games. There aren't many games packed in the game. It's organized extremley well, but that's probably because not much orginization is required.
Despite a lack in games, there is a pretty good variety so you don't have to only like track. They did take into consideration that most everyone games and there are a wide variety of gamers, they just couldn't get it through their heads this time that most gamers want a lot.
At least you don't have to have a party to play with others. Using the Nintendo Wi-Fi connection, you can go up against people worldwide. The question is who since there aren't many intrests you'll find here.
Mario & Sonic can bring lots of action into this world, but this time, it doesn't happen. We would expect a lot more from Nintendo having that they've made games longer than most companies, but apparently we are wrong this time. The only thing brought home was Wi-Fi, but how will you use it if nobody cares?
