10 hour 2nd ed game, myself as Allies and friend as Axis. Germany takes Russia around T3 or 4 but leaves Europe relatively open. I took Germany twice as UK, the third time I tried to take it back he survived by a single tank. Germany builds mass infantry and is supported by Japanese fighters, so the Allies are unable to build transports and decide to reclaim some of mother Russia to get feet on the ground.
By this point our brains are fried, ready for bed… and catastrophe ensues.
Germany and Japan pushes back to reclaim Europe, except for one thing… THIS WAS DONE ILLEGALLY, BOTH COUNTRIES ATTACKED ON JAPAN’S TURN.
Neither of us noticed until it was too late, and there was no way we were going to try guessing which countries had which units!
GAME OVER.
10 hour game, fun!
