I hope it's better than the first one. I almost forgot by the end of AC1 that the game was supposed to be about stealth because it was so much easier to charge in throwing knives blazing. Provided that stealth was even possible with the sheer number of guards the game placed in most of the missions anyway.
Well with 4 new weapons, a variety of new abilities, and what looks like a much better plotline, AC2 is sure to be a much better game than its predecessor.
