A lack of variety is what made Assassin's Creed, an otherwise fantastic game, into a chore towards the end. Assassin's Creed II, however, addresses that problem, as well as most every other problem that the original had. It's far and away a better game in every respect. Unless you have a preference for the first game's setting, you really don't have much of a reason to play the first game anymore. And for those who didn't play (or like) the first one, you really don't have a reason to not play the second.
