@Fabiusz: For one of our latest MP games, i did a buildup test run with GER...finally ending up with playing ITA
. Nevertheless, the result looked promising.
- IC buildup (+ reinvestments) until mid-1938, last builds ending in early 1939 (end of CSR event); but you won't be able to invest all of your IC after 1937 (end of second build run at latest):
- one modern HQ 39 (+engineers)-serial run beginning in 1937 should give you enough HQs until Barbarossa; same for interceptors and multi-role-fighters model 1937 (4 serial runs in total; i prefer 3:1; you might need less against the AI) and perhaps some CAS (1 series, but not mandatory; may also be built later)
- infantry and tactical bomber builds beginning in mid-1938; planes ending in early 1939 already!
- at least 6 serial runs of tank divisions as soon as unlocked + enough motorized infantry for CA bonus
- end goal for 'Danzig or War': 6 armored divisions + 6 coming up until October; about 100 to 120 infantry divisions (may be partially without brigades at that time if necessary) with at least 12 serial runs still running; special units according to individual preferences (1 or 2 paras + transport planes)
- naval builds secondary, but you should complete your BCs and CAs and some additional DDs at least for naval superiority in the Baltic Sea
- research: 'everything' besides carriers and strategic/naval bombers in 1936 and 1937; early research in 1938 for 1938 armored divisions and 1939 infantry; in 1939 for land doctrines, industrial techs, interceptors/MRF 1940 and artillery 1940
- push your stockpiles to the limit beginning in 1938
You will build infantry until early 1942 and then go for armored and motorized units only because until then, your manpower reserves will be depleted (at about 250 MP left).
Of course, you may greatly deviate from this guideline. In our current MP game, GER even managed to create a carrier fleet until 1940. But this will come at a cost for sure.
Edit about modernization: Build modern units, modernize serial builds as soon as a new model is ready (if you want to keep up the run), modernize your army to 1936 level as soon as 1939 model has been researched and focus your efforts on the units you need most until mid-1942. After that, you should have enough IC left for general modernization.
Edit 2: One long transport- and convoy-run each beginning in 1937 could also come in handy sooner or later.
