Danthraxxx I love AC4. I've enjoyed all of them, but they started to get a little stale with AC Brotherhood. I didn't finish that one until after AC3. AC3 revived the series for me. The mechanics were basically the same, but using them in an entirely different environment made me excited for the series again. AC4 built on the naval aspect of 3 (sailing and naval warfare), and it's my favorite activity in the new game. If AC2 is the last one you played, and you enjoyed it, I think you'll definitely enjoy this.
