From Gaming Bits:
"Ubisoft's much discussed Assassin's Creed hits retailers today. If you have both consoles, you still have to pick from the PS3 or Xbox 360 version. CVG has a PS3 vs. Xbox 360 Assassin's Creed comparison video, where they note the "PS3 version does look a bit sharper," while the "Xbox 360 version makes up for this with (arguably) better controls." Then there's that sketchy edit to IGN's review that Destructoid busted. On the marketing side, there's been some confusion, as Sony had its PlayStation 3 logo placed at the end of the on-air ads of Assassin's Creed (as discussed on Microsoft's GamerscoreBlog Podcast)...Mixed reviews of the game itself don't help, as evident at GamerRankings.com (Xbox 360 and PlayStation 3). If you have any doubts, you can always rent it first..."
