The pizza terrain is not based on any kind of real place on Earth which bugs some folks. But I like it. At least as a changeup to the green jungles and water we have now.
I'm not sure if airbases in the chasms is necessary. I had lots of fights ripping up and down them. And hit the walls several times. I soemtimes get disoriented as to which way is up, down and sideways after a few turns flipping thru my views in a fight.
As for the bases being mixed on the pieces of the pie, it might be a good idea to give the all country on one slice idea a try. One of the problems with Pizza is too many fields being under attack or in harm's way in too many places to find a good fight.
Xtremej, I'm not seeing the same comparison to Equinox that you are. Could you be more specific?
