Forgive me if this has come up before, but even if it has I imagine that it might be time to revisit it with DA and Guilds...
What is the fastest that a 2-player game can end, without a player resigning? Assume ideal conditions; you can set up the kingdom, make all decisions for both players, and assume perfect shuffle luck. There was a
CouncilRoom.com achievement called "The Flash" (win in less than 10 turns i.e. 9 or fewer) that was VERY tough to pop. It only happened 1,004 times in over 10.5 million Isotropic games, or about once every 10,500 games. I played 4,457 Isotropic games and never popped it.
Isotropic didn't have Dark Ages. Is Rebuild the key to a new solution? How about if both players do this with 5/2:
Turn 1: Buy Rebuild
Turn 2: Buy Estate
Turn 3: Draw 5 coppers, buy Rebuild
Turn 4: Play rebuild (Estate into Duchy), trigger shuffle
Turns 5-8: With all the reshuffles from Rebuild, I think you could draw both Rebuilds into your hand at the start of each of these turns. You need 8 total Rebuild plays to change 4 Estates into 4 Provinces. Both players get their 4th Province on Turn 8.
I don't know if that works or not. Thoughts? Logs? Other solutions?
