great game
But the city falls short due to the huge number of guards that roam around, almost 1 guard for every 2 people. Also the excessive use of horses makes you want to take to the rooftops more than ever. But also makes the town look reduced in scale. The streets seem too narrow and buildings too small. Still Roma looks awesome just as Napoleon described it... a huge ruin.
The game is pretty much the same a welcomed thing however. AC did not have many things to repair it only needed new adventures. However the huge number of guards and the great number of fights you cant really avoid make the game pretty annoying and rugged.
Also i am not a big fan of the new economical system. Buying property around town seems a bit too far fetched. I rather have a mansion to upgrade and a limited number of shops. Here however there are many properties you can buy and with such a tight grip the Borgia hold on the city... wouldn't they notice the new mogul? You can even buy Trajan's Forum (by the way: the column seems much bigger in real).
I played more of the game since i wrote the first part of this review. The game seems amazing now. It's a bit hard to enter it but after you do it it feels great. You can kill stealthy much easier than any other of the games. So I recommend this with all my heart.
