I am impressed with the changes in the gameplay and campaign mechanics.
Likewise, I like some of the new ideas in Empire. I have also been fortunate with the bugs and crashes because so far I havent had a single crash (either pre-patch or post-patch) and the game is running nice and smoothly for me without hitches or pauses. The only thing that is still bugging me is not being able to restrict my camera on the battlefield so that I cant move it wherever I want.
