Problem as I see it is: the combat in Civ5 treats what is happening on the Strategic level as if it was tactical level.
I don't see that as a problem any more than I see any of the dozens of other absurdities the Civ series of GAMES (as opposed to simulations) have adopted from their inception in order to be fun.
Complain about operational level warfare on a strategic map and you might as well complain about 80% of the other features in the game. (exploration, time scale, 1 of each building per city, linear science, worker improvements, wonders, etc)
People point to Civ5 as "evidence" that the PG system doesn't work with Civ.The problem as I see it is is they simply didn't do a good job of adapting the 2 game systems to accomodate each other.
Civ5 IS NOT the PG system. It's a lazy copy/paste of some elements of the later with little apparent thought about integrating them into the game as a whole.
PG has been "Civilized" (read "dumbed down") by eliminating key things that made it work like: suppression; support fire; sationary attacks (ie attacking without having to occupy the tile you attacked if you eliminate the opposing unit); entrenchment; retreating; supply; etc.
As such the result is not so much the operational warfare of PG but rather Civ style combat but with the SOD turned on it's side.
It's further compounded by poor decisions such as:
- Making the worlds too small and too dense which cluttered up the map and eliminated room to maneuver.
- Increasing unit costs as a misguided means of controlling unit numbers. (a scaleable support hit to production based on army size would have been better.)
- and on a related note: Making units more survivable WITHOUT CHARGING FOR REPAIRS, compounded by the stupid Insta heal.
- Making archers range 2+ instead of range 1, along with all firearms troops (and having 2 "range 1" units fight each other like melee)
I could go on and on but I don't think Civ5 could be "fixed" short of a major rewrite so it would be pointless. However I hope they don't abandon the concept come Civ6 because if they do a smarter job next time there's no reason it couldn't work.
