"I can't believe you're just giving him Australia. Australia is the key to the whole game!"
In college in the 1970s I often played Risk with a few college friends. One player would win way more often than the rest of us, regardless of whether the Australia strategy was used.
Later on, the winning player went into naval officer training, rose through the ranks and was given his own ship to command.
I like to think I was part of his strategy honing skill set.
We used to have 30-army battles over Siam. Damned right Australia was the key. Asia is tough to get and hold, but criminy! 7 armies!
