Best game of the saga, lots of fun moments, played it outside of Steam so I don't have all my 100h recorded unfortunately.

Jerry has a hook like a pirate! 7/10

+ Ezio
+ Decent characters
+ Hook blade
+ Interesting dlc
+ Ubisoft achievements
+ A farewell to Ezio Auditore da Firenze

- Feels like a mix of Brotherhood and AC1
- Boring story
- Game feels grey
- Made Desmond and Ezio look homeless
- No achievements :(
- Getting Desmond's Journey and Lost Archives to work was a pain

AC Revelations can be skipped completely (as with Brotherhood) in the grand scheme of things. The only thing "revealed" is a bit of background about Altaïr that doesn´t change anything. But Constantinople is a more interesting and flesh-out city than Rome, which was more of the same as Florence. Here, with the Ottoman influence, things look a bit different.
The gameplay is the same, the 100% synchronization is an annoying thing for completionists since it adds difficulty but there is a ton of RNG involved since on many occasions you depend on NPC to do the right thing.
The rest is the same, better than AC II, or better said, more polished, but it adds nothing new at the same time. It's an improvement over Brotherhood, but the story is even shorter and it doesn't get that tangled with the real history as before.

Oh, and you have to do some googling to be able to play the DLC if you purchased them, crazy yeah, they sell something you can't play. Ubisoft being them, but Valve allows it.
