I agree with most of what @LordCrash88 said, especially the stealth issue & that I really enjoyed splinter cell stealth way of gaming, and wished there was more in AC.

After playing unity, I still seem to find brotherhood the best one, and well the Ezio trilogy the best series,

AC3 I couldn't even continue playing the game, Black flag I didn't even buy since it's out of the series!

But unity, despite the flaws it had, was still an enjoyable game, they took the gameplay (even the interface and controls) back to normal -I mean the Ezio way- It does have a longer story than Revelations, but I still find it kind of short.. with all the graphics and the huge map and everything else the story is short! and it needed to have a bit more of a connection with the side missions..

Well, anyways.. whats done is done.. I just hope Ubisoft takes their time and puts double the efforts in the new one, and don't rush things up just to release the game. I also hope they keep the controls & interface the same, but try to add a good and long enough story to play for days.
