Im still probably going to buy the game, but i don't think it will be immediately. While the graphics weren't the improvement that i was hoping for, there are other things that they seemed to have greatly worked on. For one, the square placement method is out of the window, you can place stuff anywhere (finally) and the architectural customization looks amazing.
And where did you hear that the game isn't gonna allow customizable content? Thats still up in the air, i haven't heard from anyone that they for sure not going to allow it. I'm hopeful that EA will realize what a dumb move they would be making if they were to not allow CC. Having no CC would be the only factor that would prevent me from purchasing the game.
