Awesome mod, I've been playing it for the last week and it's revitalized my enthusiasm for CivIV. Thanks very much to the Dev Team!!
Phase 2 sounds soo damn promising as well, I can't wait to see what it has in store for us all. I saw the reference to Kal-el as well, I had thought the same originally that it was the same person, but I couldn't imagine his working on a fantasy type mod. Besides while close his username was a little different and I'm sure he'd go by that instead of making a new name. His team did some amazing work for a Realism Civ3 mod, and this mod, imo, far surpasses that one.
I do have one idea I thought I'd share as well. Especially seeing as this mod is so XP intensive. With the existence of the Hero Promotion, I get the feeling this idea should be possible. One thing I've found is that once I get a few well promoted units they'll typically make my frontline forces that tend to crush any opposition when they get upgraded to the latest and greatest forces I can build, as my typical promotion path will involve Combat V making them double strength of their normal base units, it's not always easy but generally I'll be fighting only lightly promoted, if at all, and them being one era behind makes them even more powerful regardless of city base defenses, so even without using mages to make city taking a simply nuke and walk in. I rarely need to use even siege as they're chances to win are in the 99-100% range most of the time. I also rarely have well promoted defensive units of my own, as they're not meant to be out in the wild fighting and even when I try to get them just a few promotions, it's very difficult as going down the defensive side makes it difficult to attack with them with much success, and waiting for them to be attacked is kind of dull and pointless.
Having set the tone, here's my thought, if it's possible to have a building grant a temporary promotion "Defensive Training" while the unit is stationed there (which I've seen as a promotions in the Civ Realism: Third Ressurection mod from resources and other units o I'm hoping it could be possible to affect from buildings as well) it could grant a minor hero promotion that could train units without the need for actual combat up to perhaps 10/17 xp, some small number that would basically allow 3 promotions (City Defense I, II & III). Make it so it's not a fast process, prehaps 1xp every 5 turns or so, this way in order to get the 3 promotions it would take 50 turns. My first thought was to make it either a wonder or a national wonder available at Militia. But then I figured why not make it an easily acquirable building so the AI's will commonly get it as well, which should help make standard warfare a little more difficult for the player as well by giving them some base promotions for pure defense, which considering the power of the many promotions available in this mod may not be a bad thing. Oviously there is no way to restrict the actual promotions given and I have a feeling AI's will typically go for the Combat 1-3 as opposed to the City Defense ones but that's a different discussion. It would also be quite useful for the more peaceful builder types and while it's useful it would definately have be a time based thing and not an instant promotion thing. Perhaps even make it an ability of forts to give them some further purpose beyond outdoor fortifications, this could also add to the risk factor of sending units out to train giving it an additional downside. However I'd imagine tying it to forts would make it less likely that AI's would use it.
Kinda long winded, but I hope it's some food for thought.
Thanks again for the great mod!
