Seems like a decent Sealed-Bid Auction protocol. I like how you are betting population, that was a nice touch. But you should keep in mind that a player could completely ruin thier nation in this fashion, ie: I bid 40,000 (all my pop!!) for Abysia. It might seem like poetic justice to rob that person of all thier pop, but it will make for a bad game due to the power vacuum it will create.

Additionally, I am not sure the prize system functions as you add more players. Consider an 18 player game (that is max in dom3, i think?). If I am the least bid on nation, then I will receive 9 prizes. What happens if I choose the troop prize every time? I will end up with 450% more troops than everyone else!
