Eh, not his funniest video but pretty good. It seems like he had some problems finding stuff to gripe aboud and ended up meandering a bit.
I, personally, loved Mario Galaxy 2 and it ranks among the best platformers that I've ever played and I've been playing since 1983. I don't know if he really didn't like it or not but I wish he wasn't stuck doing hate filled reviews all the time. I'm sure Yahtzee can do more that's funny than just spew bile. That being said maybe he really didn't like it but I'd reccommend it to anyone who has access to a Wii . . . I said "Wii."
EDIT1: Typo
EDIT2: Interestingly this Mario game does have some continuity if you play to the end. I'm not saying it has more continuity than another Mario title but I don't even remember another title having as much as is in the final scene.
