Amazing. Absolutely amazing. I bought my copy of Super Mario Galaxy on Thursday, November 15th. Getting into it, the controls took a little getting used to, and there was a mildy annoying reuinion with Mips, but after that, the game took off and soared.

Pros:
. Fantastic visuals; everything is gorgeous
. Classic power-ups return with a slew of new ones
. Fixed Camera, doesn't suck like previous entries (still not totally perfect-but excellent)
. Boss battles range from fun, to hard and back again
. Game takes inspiration from Mario 64 and a bit of Shine
. Gravity effects are amazing and revolutionary
. Incredible, breathtaking, original levels (the latter being harder)
. Even after you beat Bowser, there are 60 more Stars to find in hidden galaxies
. Co-op is surprisingly deep, me and my girlfriend (and my friends) enjoyed greatly-and beat Bouldergiest's Daredevil Run this way
. Some of the coolest moments in platforming (Wall-jumping up waterfalls, ice-skating on lava, surfing on shells battling giant skeletal fish in dark waters just to name a few)
. Prankster comets are an...interesting addition
. You can play as Luigi-fuck yeah

Cons:
. Orchestrated music can be...forgetable with a couple of exceptions
. Wish there was real co-op (Luigi + Mario)
. Some power-ups are underused (Boo suit)
. Prankster comets, while interesting-make time in each galaxy seem short (wish galaxies had 7 stars each)
. Like Mario 64 each Bowser battle is the same-with some tweaks

Weighed against each other, the flaws the game has are incredibly miniscule. This game is fantastic and I give it a 10.
