I love Civ i remeber when i was 3 i used to play Civ 2, I didn't know much of what was going on, but i loved it.
The new Civ 5 is a little weird.... The old mechanics such as unit stacking are gone and there are now units that can indirectly attack other units (kinda like Arty from 3 and 4) Also i heard that the game will be scripted in Lua and use Hexagonal tiles (inspired by Panzer Commander from what i have read), cities will expand along more favorable terrain (such as avoiding desert and going for more fertile lands), and their will be nations that have a second unique unit or a unique buildings
I want to get it because i love the Civ series but im worried about the new changes being a little drastic.
