Well, this mod belongs to Rocoteh, he is the mastermind behind it. I asked him prior to doing this unofficial graphics update if he was okay with it, and he agreed. I am still playing around with a few things to see if I can't somehow get the US to build more ships. The reason I believe Britain builds so many is due to the fact that Germany has 800 defense mines (and lots of them) sitting right next to Britains capital. With this in mind, I have been doing some testing to see if I cannot use this similar method (but hidden) to make US build lots of ships. It may also be the fact that some civ's have different personalities that is 'hardcoded' into the game. I have verified, that: seperating North America from South America has no noticeable effect, and blocking off northern Canada (where US sends alot of troops to, to grab goody huts) also makes no difference in US naval builds. Giving all US cities across the globe ability to trade resources makes no apparent difference, so my last guess is nearby naval threat level (MINES!).
I don't have any plans for development since it's not really my place to do so. Although I have started not too long ago filling the gap with more units (mostly all the units that have graphics created for them by all the fantastic unit creators out there). But as far as releasing anything that is strictly up to Rocoteh.
There are some interesting aspects that I have found. Such as this:
There is obviously a difference between Tank Destroyers and Assault Guns (a somewhat large difference), although some became blended such as the StuG IIIG which became a rather deadly TD. Assault Guns are more infantry support vehicles, which I have had some initial success getting the AI to make these vehicles act as an infantry support vehicle many times (with only minor changes). The AI may have them run along with tanks also, but it also has them tag along with infantry many times, thus helping them to protect the infantry, and also providing indirect fire with ZOC and defensive bombardment, but not being tank killers such that Tank Destroyers have the job of doing. Opens up some interesting new possibilities of tactics with infantry and makes the AI look like it's a genius.
I'm really just doing this because I think this is one of the coolest mods ever developed. As I go, I'm building off the stats off units already in the game, and I've put together a database of statistics for tanks, artillery, TD's/Assault guns, AA's, half-tracks, SPA, etc to measure what their values should be depending on stats, as well as actual battlefield success, industrial capacity of that nation, etc, and if the AI will use them well, or build them. (I've dug up all the tests I did on AI unit builds, as well as what others have discovered from back in the day).
I haven't heard from Rocoteh though in some time, he said he was going to be away from any Civ3 projects for some time while he recovers. I wish him the best and look forward to hearing from him again.
