This game is pretty short though it took me like 2 weeks because I was busy. There weren't a lot of side things to do and a lot of the missions were short. The map is small. Louisana looked okay though the other two locations looked good. I liked that there were 3 "versions" of Aveline.
I couldn't really get into the story which is always the case when it comes to this franchise, but this one definitely has one of the least interesting stories in the franchise. I felt indifferent with Aveline, there was just no spark. I liked that Connor appeared here but his interaction with Aveline was a non event. The ending was kinda lame. I was expecting something more exciting for the final missions but nope. It really felt like a side Assassin's Creed game. The missions were pretty easy. Though there was this very long mission in ichu. I died like ten times in the canoe, the swimming was annoying, lots of climbing and the puzzle was so confusing.
My other problems: I didn't like using the canoe, it doesn't move smoothly. Aveline swims quite slow. I can't really kill the witness without its pals attacking me. The DNA tracker looked bad. There weren't a lot of side stuffs to earn money, and I finished the game without purchasing all the upgrades, weapons and watches simply because I didn't have enough money. I didn't really use the trading menu, I just wasn't interested into it.
Overall, this is the worst Ac game I've played. But considering, it was originally a handheld game, I guess its not so bad.
