Hmm...
You guys have really pulled off something. That map was really cool looking, it made me a chuckle a bit.
I think to help create some balance for the game, you would need to be able to edit supply consumption. First, you should up the consumption of all the units considerably (this causes you to waste more of your economy on just maintaining an army rather than expanding it or making it better). Second, since Eastasia is an incredibly efficient country, lower its supply consumption quite a bit. I think for the slave states, you should make the infrastructure very low (but only if you could make it so it didnt cause attrition to the unit, just made it hellishly slow) and make the capital (Tahiti, Goldsteins impenetrable fortress

) of the Slave States have a ridiculous amount of IC's and resources and MP, but maybe at most 5 transports (they couldn't make anymore).
Also, I think the countries should have an endless amount of resources and supplies, and shouldn't worry about MP (they should only worry about the cost of creating and maintaining an army

). The countries would have a fairly high IC count, maybe about 1000 each (not the slave states mind you).
1. Eastasia: 1200-1500 IC's
2. Eurasia 900-1300 IC's
3. Oceania: 1000-1200 IC's
Note: the last two countries should have lower IC's for game balance, and also they supposedly went through a massive nuclear holocaust. The IC's of the last two could possibly be lower to make it even more balanced.
Finally, my opinion on boundaries (just my two cents). If I remember correctly, Oceania actually had a fair amount of holdings in India (remember Winston reading about "our boys out in the jungle" or something like that). Also, I think the Phillipines and parts of Indone- Malay- sia should go to Eastasia. Give Oceania the Aleutians and Hawaii. Also maybe instead of making a Slave State, maybe make some "unclaimed" territory? I don't know if this is in the least bit feasible, but it would simply be land that had people living in it, but they had no allegiance to any country. You could not annex them, nothing like that, you could just occupy them. It would be able to change hands multiple times. If that isnt possible, just make those provinces have 0 IC, ) forts, 0 AA, and maybe like 20 Infra.
I think thats about it, and I am sure some of my stuff has already been rejected or it is impossible, but I am just trying to help. I would like to get my hands on this as soon as it becomes playable, I am just trying to speed up the process.
Great stuff, keep up the superb work 1984 team!
