Excellent Mod! is what I was looking

if I can suggest an idea...
1) If you can in the next update, put more ethnic diversity as Marines and other units of powder.
2) And more female leaders to the power!

^^
check out this mod, I think you can give some good ideas to expand the VIP

1) There was 1 thing I constantly kept in mind when making this mod, and that was size. Size of download, size of memory consumption, size gained by various optimizations.
The main reason for that, is Civ IV is a 32bit application and therefore cannot use large amounts of RAM. If u tried other big mods, you'll most likely come across "Memory Allocation Failures" or MAFs, which are pure gamebreakers. Putting alot of stuff into VIP and still not getting MAFs has been alot of hard work. Lots of other mods put tons of units (some actually puts ethnic diversity for each civilization) with the result of a game that cannot be played to the end (or atleast on large+ sized maps).
What I did was to split ethnicity into groups (as it is somewhat in Civ Bts Vanilla) but adding a few more (African f.ex) and adding different units for those ethnics (mainly from the Civ's own install, as lots and lots of Firaxis' units were never used) up untill gunpowder. I then changed the gunpowder units so they had team colors.
Main reason for selecting individual ethnic units for early eras is, imho thats where there were most cultural differences between people.
With that being said, I have later moved to a more "modern" computer, that supports 64bit (the game is still 32bit though). And while adding I cataloged/categorized tanks/planes/ships into era and role, so that I might one day add ethnic modern units

TL-DR - Not at the moment due to memory restrictions, but it might come later.
2) I have always wanted to add LOTS of new civs and leaders, but during development these extra "packages" would just make heavy uploads/downloads.
It wont take long time to add civs/leaders (from the mod u gave me for example), but as you can see, the size for civs/leaders only is 3 times that of VIP (which adds TONS of content) and the reason why its only 3 times is because I recently added the VIP Loader that gives the option to select from 4 different terrain textures, otherwise it would be around 5 times.
with (all) that being said, I have to admit that modding have slowed down considerably lately, as I had a son (for about 7 months ago) and he doesnt (yet) understand the concept of neither civilization nor modding and the relative silence/concentration both requires to perform optimally.
