I did something similar to that [one time](
http://warlight.net/MultiPlayer.aspx?GameID=1154742), only I made it a practice game and I surrendered the game anyway.
I thought I was being pretty clever. I made Alaska, Hawaii, and Japan worth 20 armies and Korea worth 1000 but on the map it appeared that Korea was be worth only 10 because the box will only show two digits. That could just be my monitor but I doubt it. If you hover the mouse pointer over the box it'll tell you how much it's worth anyway.
My hope was that some clever player would have noticed my treachery and then have made an attempt to counter it, but I was gambling that they wouldn't have noticed that Korea was worth more than just ten.
Unfortunately, nobody noticed until they saw my huge stacks.
I still think it was amusing and I would have thought it was funny had it happened to me, but that's just the sense of humor I have.
I know you're not always expecting douche-baggery but I always do a quick scan of the Settings menu of the games and tournies before I join them. One of the things I look at is the overridden bonuses in the bottom right corner of the Settings menu.
Anyway, I wanted to share a story I thought was mildly amusing and make everyone aware of the Overridden bonuses area of the Settings menu.
