A;though, I will admit... The Best strategy game I ever played was DEFCON... But, it was with a twist, so read on:
There was a group of 4 of us... We were all working repeated 10 hour shifts in a call center, since it was basically shutting down (All of the other staff had been made redundant and had been given severance packages - we, the graveyard shifters, were "essential components" until closing - yes. We were components.)...
So I'd snuck it into the system, and we'd fired it up - playing it in 2x Realtime Speed... DEFCON is wonderful in taht you can actually play it in REAL TIME... Which makes hurling insults at each other across an empty hall of open-plan computer systems awesome.
We had put stakes on it... The place was being cleaned out, and we'd found the Fridge had been stocked with Beer for the Party the Next Day for the redundant staff... But the fridge wouldn't close properly... We removed 4 Slabs of Beer from it so it would, and those Slabs became One Each - Take it from them if you Can! prizes...
It was freaking glorious... Especially for Maude, our 75 year old ex-retiree who had been forced back into the Workforce to pay for her Children's Debts... Man, she was a cranky, but fun old hag... She almost took the endgame from us with her SLBM strike of doom from the Indian Ocean...
The alliances we'd worked over messenger were positively byzantine... I think I walked away with 2 and a Half Slabs, even though I was the second player to "lose" that day...
