I've only played two skirmishes versus the CPU so I can't really comment on the gameplay, but the GUI is horrible in my opinion. Everything has been made really cartoony and the information bar along the bottom takes up approximately 1/3 of my view. I do like the notifications which pop up on the left hand side though, warning you of various things such as mortar bombardments and units entering the battle. I'll have to play a bit more but right now I feel like I spend half the time scrolling into a position where the camera is semi useful due to the massive obstructions of the GUI. The information about the history of your units and the information about selected buildings would have been better presented as a mouse-over, or as a separate codex type thing in the menu, instead of being ever-present in the bottom centre, in my opinion.
