I doubt they change much, to be honest. One of the hallmarks of the PC version of Civ is the awesome amount of control it gives the player to design their own game. I've had some that lasted weeks after I set conditions like domination only on the biggest maps with the most number of civs allowed.
Civ:Rev appears to be the exact opposite of that perspective. In order to simplify it for the console, they have stripped much of the depth, and in doing so, balancing issue probably won't allow for much customization.
As soon as I obtain all the 360 achievements, this sucker gets sold and I go back the complete version of Civ that I have known and loved for many years (take your pick, II-IV are all great, IMO).
