I have both but am pretty disappointed in them.
Mario
Kart does nothing new. Motorcycles, big whoop. They do nothing. Plus, eliminating snaking instead of just adding a non-snaking mode was a stupid thing to do. It's almost as if the devs said, "you shall not have any skills in OUR
Mario Kart." A disappointing game, albeit fun just like any other
Mario Kart.
Super Smash Bros. Brawl was initially mad fun but the Smash
online community is too hardcore for my tastes. The game is also very much like its predecessors, and the Subspace Emissary is just 8 hours of pushing forward, reaching an area with enemies, eliminating them, and repeating. While I find it a great game, it's not without its flaws.
Long post was long.
