The jump in quality from 1 to 2 was absurdly higher, but it's undeniable AC3 was the superior game in every aspect. Aside from the story which, of course, is opinion-dependable, but in that regard I also believe it is superior, though not by much, as AC2's story was superb.

ACII was just so easily the best of the series, as far as an overall game goes. Revelations, in my opinion, had the best gameplay: Hookblade, bombs, poison, crossbow, just EVERYTHING added up to giving you an excellent variety to work with. But as an overall game, AC2 was just so good. The story was excellent, the character actually went through an arch, and the gameplay was just as solid as the rest.

II. Though I enjoyed 3, it felt extremely clunky to me. Its the most angry I've been at a AC game. I swear I almost broke my controller while chasing Lee. And I just didn't like the ending...and Connor was kind of a dick.
...and I heard as it were, the noise of thunder. And I looked and behold was Death saying, come and see. And I saw. And Hell followed me.
