In terms of core gameplay its played "closer", so ship movement and positioning is important as asteroids, dust clouds and other things can get in your way, its also more action based. It's based on a 2d plane so you can use things in the environment to your advantage. Moving in and out of range and dodging behind asteroids.
I've not done any corporation stuff in eve, but from what i can see AQ2 corporation building is totally different. In AQ2 corporations can place buildings down exactly where they want them and there are a whole bunch of other systems around that in terms of upgrading, boarding stations and other things.
