I knew I was going to buy this from the reveal, the game being the kind of longshot reboot that you rarely see (from Nintendo, anyway) outside of pre-E3 wishlists. I was sold based on that, Sakurai and what little we knew about the games systems. Everything we've heard in the past several months has increased my hype exponentially. The multiplayer looks awesome, there's tons of content/replay-ability and the difficulty slider is very welcome. It even has loot, which I'm a sucker for. At this point it's my most anticipated game.
The most recurring worry and criticism is that the ground sections can be difficult to control, but the EDGE review made it seem like there's a learning curve, not that it's unplayable, so I'm not too worried about that.
I'd love for this to be a success and for the franchise to take its place with alongside Nintendo's most beloved IPs. Already dreaming of a Wii U version.
