I´ve converted 30+ maps from Civ2 to FC. You can download them from the Freeciv discussion thread in the Scenario league.
Skeptics should forego any thought of convincing the unconvinced that we hold the torch of truth illuminating the darkness.

Doubt is humbling and constructive; it leads to rational thought in weighing alternatives and fully reexamining options, and it opens unlimited vistas.

I post the maps here too for reference. Some people have had trouble downloading them from location above.
Repackaged to include gigaworld.sav into the zip.
