writting this after almost 70hrs in the game, its the most assassin's creed we got from an assassin's creed game so far since ac4 (althought ac4 mostly consisted piracy and naval warfare, it still had quite a lot of assassin's creed-ing to do). tbh, this is the best entry since ac4, and ties all the games together very nicely even the present day parts, the gameplay is quite great although sometimes suffers from the controls and bugs ( i will get to the bugs in a bit), story is really good and the side quests are not mundane anymore they have really put a lot of thoughts into the side quests as well it reall feels like a lively world and your actions do have an impact on this world.
now coming to the bugs and glitches, its a storehouse of bugs and glitches and crashes. it has numerous glitches (some quite annoying and game breaking and some being really funny just look at, for example, i foung a boat floating above water it was a great moment XD). the crashes are quite annoying although ubi is working on polishing them out bit by bit.
to summarise its quite a great game if we overlook those bugs and crashes, worth every penny if you get it lower than the 60bucks it actually costs but at full price its a bit of a negotiation, i would say buy it during a sale.
