I would much rather have a polished and completed current-size Balkans theater, in the vein of the official Korea theater. With nicer tiles, perhaps the new terrain/ground in the new version, more detailed air-bases with consistent navcharts, with bug-free ATC and autonomous campaigns (where no user input in regards to ground war and ATO is needed to complete). I would even love to help out with that, but no idea where to start apart from reporting issues.
