Thanks for trying this, Tholish. It may not have been clear from the first post but this is only the first 1.25 eras of the tech tree. (therefore we didn't post this to the completed mods section!) We are right now spec'ing Era II, which tells the story of the different lifeforms that arise, and on the horizon are Eras III, IV, and V. (The eras are Survival, Adaptation, Growth, Awareness, and Ascension).
Also in Era II are the first real assault units, very analogous to the Classical/Medieval units in vanilla Civ4. There will be Tanks, Infantry, Bombers, and units unique to each of the lifeforms with their own "flavor."
I like your ideas about custom barbarians... tho right now our problem is that they die out too quickly. Our solution will be to put them in the ocean, where humans can't go for some time, but that requires SDK work...
I fixed the terrain bug on the latest revision, but that was posted late last night so you probably were playing the buggy one. Thanks for putting up with the nasty pink, though!
I welcome you to jump into our
discussion space and put in your $.02. We've got a very active thread right now going on what units we want to see in Era II.
Thanks for your feedback, and hope you'll join the team!
