I got to play Super Mario Galaxy a couple nights this week, before my copy arrives from Amazon next week. As I commented on Nick's blog:
I am consistently disturbed at how shiny and fuzzy everything is. And Ice Mario... I think the plumber has been in the Mushroom Kingdom for a little too long. Perhaps the curious placement of stars in the logotype was not an unfortunate accident but a warning.
But the game is totally fun.
I picked up the habit in playing the previous games of replaying worlds immediately, so I crowned a few of the regular galaxies. I had Brad's copy for a couple days and got to the Engine Room, so if I'd had it for another day I might have been able to return my copy when it arrived (until I wanted to fully complete the game, not just beat it).
