I was meant to take out MAS. My aim was to take the Midatlantic region (and it's benefits)and head south, hoping someone else would knock him out out west. That didn't work, obviously, so instead I was going to wait for ernest to destroy him in the south and try to get him out west.
I never took out either half of MAS's territory tho I could have easily have done so earlier by concentrating on that half because I was worried that someone would have the mission to conquer him, so I didn't want to make it easier for them. The possible missions out there caused me to play as much to avoid helping someone else to win as it did to actually win.
The staunch defense of Virginia did extend the game by a turn for at least Josh. If I had taken Virginia without any loss in Round 5 I would have tried for the victory then, but they defended so well, that I couldn't even execute my backup plan of taking out Josh in Maryland to get his RISK card. I didn't even dare try taking Josh on 8 vs. 8 since if I failed and someone had the mission to conquer him, I'd have made it easy for them to do so.
