yeah absolutely, but then we’re in the same boat as campaigns…
There are sensible options even with the current tech tree concept, but the maps simply have to turn generic rather than actual locations.
For example, here’s Raf’s pluck of the week on how to unf@#% Enlisted.
Make all maps generic - some that look like the Eastern Front, some like the Western Front, some like Africa and some like the Pacific. Piss off all the wrecks and other BS pretend senery rubbish, there will be enough wrecks and craters on the map once combat begins. They should play into the destructible terrain ace card more - sure you can start off on a map with more buildings but as shit gets blown up the map tends to turn into a moonscape.
Configure the tech trees into Axis and Allies and insert all the minor nations that played out on each.
So allied US / British can fight randomly on Western Europe, Africa, or Pacific maps, whilst some of the minor nations would only fight on European, African or Pacific maps depending on historical deployment.
For Axis, Germany gets them all less Pacific, and Japan is the reverse. Minor Axis powers would mostly get Eastern Europe, with a sprinkling of Africa.
Separate the tech tree into early / mid / late war to create the current 3 queues. When a player has selected a squad within a nation they get added to one of the queues, and are separated by the 4 available rough geo regions depending on what faction they selected.
Early war can include the Russo / Finnish or even the Spanish civil war, so you can start circa 1938. The cut off would be end of 1942. The mid war would be 1943 - 1944 inclusive, and late war is 1945+ where you can chuck in all the wunderwaffe your dev hearts desire. For vehicles that span these years put in some bloody effort and separate them out by gadgets and upgrades which they would have received in service.
Make the equipment cut off historical, and balance accordingly - if you’re missing stuff for balancing then that’s just an opportunity to create some new things and sell them to us. Tag the equipment with an additional MM marker that would reinforce the map dispersion algorithm, so bits of equipment that were used in Eastern and Western Europe would help discriminate further which maps your squad gets based on how you equipped it - ie some weapons saw service in a particular theatre of war and if you just wanted to play those maps you could bias the MM by equipping the appropriate weapons, same for Africa or Pacific maps.
Limit the number of automatic weapons, by going back and implementing the correct national and historical sections/squad based load outs including squad sizes !
Allow only one of each squad type in the line up, and then the random premium slot, which could feasibly give you a second type of unit in your line up, depending on what you chose to slot in there.
Done !, just in time for tea and scons.
