Assassin's Creed

Ok, so this was announced sometime ago as a PS3 exclusive, but as most of you know it was recently (months ago) announced to be coming to the 360. I never took much interest in it until after I seen <a href=“http://www.youtube.com/watch?v=PcNoy8rdvtQ”>this</a> gameplay demonstration video. Now I’m totally stoked about it and it has me wanting to buy a 360.

Does anyone else happen to have an opinion on the game?

If it turns out to be sci-fi it’d interest me. If they keep the ‘based on historical events’, the ninja-ness will be too much for me (!).
