Actually I was talking about Civ III LDiCesare but yeah Civ 2 had a very advanced unit editor... in fact I thought Civ2's unit editor was almost perfect really.
I would still play Civ 2 actually a lot if not for the poor AIs (Civ 3 and Civ 4 had a lot harder AIs) and the 7 Civilization limit. I also thought the cultural borders and uu plus ub was a huge upgrade. As this thread mentions, other areas where not a big upgrade. Civ2 had better (and more historically accurate) scenarios than the other two. Rise of Rome scenarios for both Civ III and Civ IV are dissappointing... where are the diadochi kingdoms? WTH is Persia still doing in the game, didn't Alexander crush them. Egypt was ruled by the Ptolemys and should have a Greek feel. Why is there a Greek civ that owns Macedonia, Achia, and Asia. Shouldn't they be split up into Macedonian, Achaean League, and the other Greek leagues/city-states. Where is Thrace, Numidia, Pontus, etc.?
Then there is the Civ IV Charlemagne scenario where the Saxons are in Poland and Bohemia is like in Russia (way off geographically) or the Crossroad of the World scenario which had the coastal city of Antioch way inland and butchered geography.
I really thought Midgard, Jihad - Rise of Islam, Crusades, Napoleon, Mars, Dinosaur, etc. scenarios for Civ II rocked.
