Prepare to buy a game that has been made made for money.
Story of Desmond makes sense, but Ezio this time around looks like a fantasy character. How can a guy that's 55 climb huge buildings? Same with Altair, he climbs till he is 90. But the game has explained Altair's death perfectly. We have a few legendary moments. "The End Of An Era". You finally say goodbye to Ezio and Altair. It's sad, but thee characters have gottten old.
Gameplay: This part of the game is a copy paste of AC Brotherhood. Only differences are the hookblade and bomb crafting. Bomb crafting is OKAY. Hookblade was great. But that feels like it should have been downloadable content.. Which makes this game horrible. Multiplayer hadn't changed at all, just a few small stuff added and new characters. Otherwise the game is the same.
Assassin's Creed Revelations is the biggest disappointment in the series. But it reveals valuable things in the course of the story. Although this game should have been downloadable content for 20$. But it's a game sold for 60$.
