After playing a number of random scenarios to get the hang of the game (if you are new, keep playing until you wipe out the AI, it is good practice).
This reminds me of my second board game Africa Korps by Avalon Hill (Blitzkrieg was the first) before the days of computer games (I think the first computer wargame was Tigers in the Snow). However this Africa scenario is much better and captures well the ebb and flow of the Africa Campaign.I almost had dierrhea when my German units were mostly dwindled to 2-5 action points, and massive replacements arrived just in time. Actually this helped for the following reason.
I had reached a line approximately halfway between Tobruk and the next city when the Allies broke through in the South. So I had to retreat everywhere to avoid annihilation in the lower half of the map. The AI of course reacted by forging forward and did manage to get on of my HQs. However the German and Italian replacements allowed me to stabilize my line, and do do a southward encirclement maneuver with my renovated Panzers from the North of the map.I managed to destroy most enemy units in the pocket.
So at this point, I am well past Tobruk and on the offensive. The visible Allied units are weak and unless they have massive reinforcements coming soon, the British might be in big trouble. OTOH, more fighting will eventually attrit my units to nothing once more, and as the front width shrinks, encirclements will become more difficult.
I havent checked out the replacement list, so I have no idea if I have broken the Allied back or not.
