@argothair RE: Wheat, well, I do happen to have the resource tokens lying around. :) But rules-wise, totally - they would both want to just fall under a “Resources” heading with identical simple mechanics, like:
Resources (optional rule)
Securing special resources like oil, wheat, iron, and rubber was crucial to the war effort for every belligerent power. Territories where these special Resources were particularly abundant are marked on the map with a corresponding symbol or figure.
During the “Collect Income” phase of your turn, each Resource you control grants you +1 additional IPC.
Resources do not increase the number of units that can be mobilized in a particular territory, and they cannot be moved or destroyed by any power.
RE: China, I’ll try the ‘guerillas/no blitz’ rule in my next solo game, along with the ‘Version 3’ map above.
RE: VCs, I agree different thresholds is fine and totally historical.
I may also try adding a Siberian territory and re-jiggering those IPC levels as well. Buryatia goes to 2 for Vladivostok and lend-lease, and maybe Far East stays at 1, but the rest could be zeroed out in favor of the Ukrainian resources discussed above, or a boost to Archangel for lend-lease?
I love convoy rules, of course, but I think that’s too much for AA50.
