I think it's more like Assassin's Creed. JaseC wrote about it a few pages back.
I've seen people say it has more in common with Hitman than AssCreed, but I've never played a Hitman game and it seems kindasorta AssCreed'ish to me, so needless to say it has my interest. Once again, though, Focus hasn't provided any pre-purchase incentives and with all of the other pre-orders that are on my radar I don't know if I'll be able to justify pre-ordering it.
