I recently watched yet another video about Assassin's Creed II, and the only thing I was thinking about was when I can get my hands on it. Similarly, I did this with Grand Theft Auto IV. I think that AC and GTA undergo a similar development scheme. Grand theft auto: San Andreas was marvelous, but it just didn't show off the hardware of its time. When GTAIV came around, it was top notch, and fully took advantage of the market's prominent hardware that would be available for consumers.
With Assassin's Creed, I'm finding the development to be the same. ACI was marvelous, but really didn't take full advatage of the hardware nor programming methods such as AI scripting. ACII seems to be using full deferred rendering and scripting seems to be the best of this year which would lead be to say its also gonna be the Best game of the year.
Grand Theft Auto and Assassin's Creed have both made vast improvesments to both of their games and I like how both of their development is going.
