I gotta say, after playing Civ3 again recently, I can't give much credit to the warring/combat systems in it (i guess Civ2 used a similar system).
You randomly get 'promoted' to veteran/elite status? ugh... And I could never tell if my unit won a battle he was defending in unless I turn off fast movement. Uniques simply had increased combat/defense/or movement. Boring...
I dunno, maybe I'm just used to Civ 4.
