Greetings! I have considered a DAW replay for my next project. I don't quite like +5 Manstein or -5 turns, as those heavily reward map pre-knowledge, especially air waves, so I have settled on the following rules:
1. One-of rule: only buy 1 active unit of each type. (Exception is if a hero spawns, like on map 1! I have two of the Hs 123 bombers). This significantly makes a mechanic-abusive run filled with Branderbergers, which I had previously determined was the most optimal play, not possible. This also allows exploration of all unit options, as I had never used, for example, non-EL units in previous playthroughs. This also encourages spreading out SE units. This also limits abuse of the airforce.
2. Flat 40% prestige. A bit harder than Rommel but not crippling pennypinching.
3. +1 enemy strength starting in 1936, and perhaps +2 by mid '39-41 campaign, then +3 in '44-46, when we have all of our tools at our disposal.
Experience has already been reduced by campaign settings, so I won't touch that further, as it leads to tedious experience farming.
1. Dresden. Ended turn 16 due to reserves being almost completely wiped out. We likely would not have been able to penetrate the 16 strength MG nests near the final objective, so we took the liberty of sneaking the last victory objective by horse.
2. Breslau. Up to now, SE Jager and Bridging infantry are my units. We have to do a bit of game-mechanic abusive strategies of allow capture then recapture of defensive victory points; even at 40% prestige, they get us back ~300 prestige just from these four alone!
The latter half of the map goes okay; however, the mud along with wave of four additional enemy aircraft along with the untouchable forts surrounding the last objective force us to take the early win again at turn 24/28.
Note I am still trying to avoid during-map replacements unless absolutely critical to hold a hex.
Edit: A major hindrance is the availability of only one core 3-range artillery piece at the moment, given the one-per-unit rule.
3. Starting Obserschlesien, our first non-hard map, with 1102 prestige! The map also features an exit hex, which is phenomenal. We can save units and sell that for their full value; we also can use these hexes to re-use non-core units and still save them for the future. A major feature of the Allied campaign, not all DAW main campaign maps have this. My previous attempts have always been to try to grab every last flag hex. I think we will have to be a bit more judicious in force preservation here. Instead of attempting anything more than necessary for DV if possible, we will focus on saving as many auxiliary units as possible. There is about 3700 prestige worth of aux units on this map. (I am actually curious if the game is winnable on 0% prestige using just sold units..! We also still have 14 deployable aux units from the second map.
