Thanks for the heads up, probably pick up a copy or two as gifts.
I actually prefer AC1 to AC2, I just couldn't take much of the dialogue seriously with the over-acted accents in 2. Then again, I also liked the pacing of the story far more in AC1 as well, so I know I'm certainly in the minority.
Gameplay wise, AC2 just has way more to do. But as far as story, I prefer AC1.
