On normal long games who usually ends up winning the game: the axis or the allies? By long I’m going to say 8 turns+, if you wish to debate the turn number I set please feel free to do so. And by normal, I mean a game in which there has not been EXTRAORDINARY game breaking luck, or an EXTRAORDINARY oversight by a side.
Examples of each: Germany attacks Moscow with 30 Tanks, Moscow has 20 INF for defense and Moscow wins the battle leaving Germany crippled. Or the US or Japan don’t notice a lone transport that hits their capital, things of that nature.
If you happen to notice why you think a longer game tends to favour 1 side over the other feel free to state why.
This post assumes no one is playing stubborn as well. For example: if moscow falls, and the Axis are all alive, kicking, and doing fine I would consider that a game over.
