Unless i am totally blind all the outcomes as long they don't end the campaign awards the same amount of prestige no matter if DV, MV or even loss. Here is a dirty and quick list of it. If wanted i can incorporate it into the tree later.
Reconnaissance in Force 500 Ras el Mdauuar 700 Brevity 900 Battleaxe 1100 Dash to the Wire 500 Second offensive 1500 Gazala Line 1700 Malta 2100 Alam Halfa 2500 Suez Canal 2500 Palestine 2700 Syria 2700 Iraq 2900 Basra 3000 Persia 3100 Caucasus 3100 Arabia 3300 East Africa 3400 On Road to India 4500 British India END El Alamein 2100 Kasserine Pass 1900 Mareth Line 1700 Tunisian Bridgehead END
It's actually hard to lose Alam el Halfa, so I recommend you play it through then on the last turn, use the cheat code (shift-ctrl-alt-"c") and enter "end scn 2". End scenario "2" triggers automatic loss (0=dv, 1=mv). That is how I accessed that path. And those scenarios are well worth playing, all are fun and challenging, as they should be.
It seems like whether or not you win (either decisive or marginal) or lose Dash to the Wire, you end up moving to the same next scenario. So why would you want to fight Dash to the Wire and risk losing your core units for no advantage? Thanks in advance
