I'm glad someone will pick the mod up! I really wish you good luck, and will give you all the support I can (unfortunately, not much right now...).
As I have told on another topic, my PC is broken - so, until it's fixed, I'm without Civ 4 and without any of my files. There were older versions of the mod, some info (including quotes from the books for every tech, the image of the full tech tree, etc), and some 2d art... Thought I can look at the forum ocasionally, I can't mod for now (and 2 weeks from now I'll start college and perhaps work, so I likely won't have plenty of time until July). Anyway, when I get my pc back you may count on my occasional help and feedback...
If you overcame one of our CTD you're a much better modder than I am (we had plenty of them, and allways had to start over). I didn't even knew where to look for them... Anyway, if you have any tech file, I may assure you it's working; it was the only file edited by one person only, and I tested it separated from all the rest to make sure it was fine.
About making the mod from FFH2, it was a recent idea. We didn't actually discussed it deeply, and don't know what we would take and what wouldn't fit. I think it's great, it has many mechanics we could use: heroes, unique resources, world "spells" for civs, etc, etc, etc.
