I like the game, story is very nice, music and gameplay are awesome and regarding PC controls, is a big improvement over ACB. Also some of the side missions are great.

I really like the new "Hookblade", it makes climbing and jumping on rooftops more quicker (and more fun).

Regarding the Den Defense (the Tower Defense minigame), I think it was an interesting idea that didn't work very well. It makes sense to defend your dens, after all templars are not milk drinkers, they want to capture the dens previously lost to the assassins and reclaim that area of the city. However it is boring and there are a lot of better TD games out there.

Mediteranean gameplay is alsog ood.You can play it when you want to take a break from usual gameplay, or after you've finished the game, or if you want to level up your assassins.

Multiplayer is also improved over ACB, but I have to play more in order to have a solid opinion on it.

However I miss the Virtual Training from ACB. It was quite addictive...always making me want to be better on the leaderboards :). But probably not everyone enjoyed the grey textures...I didn't watch the forums to see the other impressions about Virtual Training.

Overall, ACR is a good game, possibly the best of the series (maybe because of the story+gameplay+music combination which is really great).
