" @Jeff: Great thanks. I've found the achievment comment sections to be one of the most useful things on this site, makes looking for tips about 100 times faster than when I had to go hunting through google. "
Probably the best place to get tips on achievements is xbox360achievements.org. Full guides for all but the newest games (and guides are put up pretty quickly for those, too)
Finished it last week, glad to be done with it...still hoping to get the first comment on a video at some point. I've gotten as close as the 3rd comment, I believe. #297 to finish the quest set containing super sup check.
I'm only about halfway through it. I'd be even closer, but after the first week or so, I forgot one day, so I had to start over. I'm glad the time they use is their server, since a couple days back I updated after midnight my time.
