Wrapped up AC IV. Was a really good time. I got used to the ship battles by the end but I would have enjoyed that aspect of the game alot more if it didn't take so damn long to upgrade the ship. A damn fine game though.
I've not played IV yet, but the ship empire and materials components to Rogue were the weakest parts of the game for me. You have this fleet of ships that you're sending all over the world to trade materials at various locations...but you can't actually use any of those materials for upgrading any of your shit. By the end of the game I had ridiculous amounts of money pouring in but kept having to run around to buy wood or oil or whatever. Terrible implementation of the trading idea.
