Thread necro time! Quite some time ago I hinted a Freeciv 2 port, and I recently got a nudge, so here it is. It's currently at version 2.4.4: http://bszili.morphos.me/ports/freeciv2-mos.lha

They released 2.5.0 just a couple of days ago, but I don't think I'm going to update until the next major version is out. Bugfix releases are a pain to follow.
I couldn't test the gameplay much, I'm not very adept at strategy games.
