It's a LOT more realistic than civ5. On the macemen beating tanks, I've always thought that the solution to that problem is to give an automatic win if a unit has > x% odds (like in civ rev). As for healing, what's wrong with that? Wounded men get better and reinforcements arrive. Civ4 doesn't have units transmorgifying into boats, archers firing over the English Channel, or leaders who will betray you the first chance they get.
Trying to force tactical combat on a strategic map has far-reaching implications. It's the reason for the low tile yields. It's the reason the city maintenance mechanic (they only mechanic that has ever worked at curbing ICS) was abandoned in favor of a seriously broken happiness mechanic (with the return of building maintenance). The developers had to make sure cities never became any good because then there would be too many units on the map.
sorry if you were insulted I definatley didn't mean to.
Yes Civ4 is more realistic than Civ5 I wasn't attacking that aspect, It's just that when you criticize civ5 you shouldn't point Civ4 as something optimal, because it obivously isn't.
It's good, better than civ 5, just in no possible way realistic.
When you imagine a battle, you imagine there were casualties and if you fought with your army in another continent for example and if you get half of your army killed, I can't Imagine them simply go back to full squad miles and miles away from your civilization in the middle of a desert if you wish so.
Also agree with city maintenance

Civ4 had it nice way but it was far far from perfect. I think they should build on that.
I also don't think they should ditch the global happiness because it can coexist with city maintenance. I imagine the global happiness as a sort of "civilization stability". So I think there is no need to throw that Idea out of the window, just add on the concept and I think over time, there might come up something good.
But I still want better AI before anything else gets fixed.
