I downloaded the latest version of Freeciv tonight, 2.0.5, and it seems they have significantly upgraded it from versions 1.x. I have some saved Freeciv games online.

If you've never heard of Freeciv, I suggest you go check out their website. It's quite fun, but can be rather addicting, and is great for some instant enjoyment. One builds cities and settles new land in the pursuit of building a great civilization.
