Comparison of Freeciv's civ2 modpack and Civilization II

From Freeciv

Despite a stated desire for compatibility, not everything in any Freeciv application is the same as in Civilization II. See the Civ2 page for some background and a link to some old discussions that list some of the then differences.

(Who is keen to pore over those discussions and compare the latest version of the civ2 modpack with the commercial game?)
