There have been talks about a Civ-2 -> Civ-3 scenario conversion-tool ( hence:
http://apolyton.net/forums/Forum6/HTML/002645.html?7 ). Thats great - the more they can re-exploit past Civ-2 scenarios into Civ-3 as well, the better it is. Besides, designing scenarios is hard work and those who have put so much work into it in the past, perhaps deserves a second updated chance to show off their old stuff.
Another potential goldmine-source is MAPS. Im not only thinking of some kind of conversion-tool here. Also, it would be great if Firaxis, a few short months before the Civ-3 gold-release, would pre-release a sparse cut-down version of the map-making tool - downloadable from their site.
Nothing fancy: not with scenario-functions - just the barebone MAP-MAKING part of it. Lets face it; the map-generator has its obvious AI-limitations and it can only be a good thing if Civ-enthusiasts manage to crank out an ample selection of
handcrafted maps to play on, once the Civ-3 is available in the stores. The way I see it: it would be creative fun for us fans while we wait, and at the same time; Firaxis gets some nice raw-material for Civ-3 maps for free.
