It would be another spoils option. To win the game, a player must cash in X amount of cards that are owned by that player at that time (bloded). Maybe X could be a variable, or could be set to 5 or 3 or 10 or something, i dont know. Anyway, when "player J" plays cards that he/she owns the territs for, it could be noted in the game log. The side stats could show how many more spoils that player needs to turn in to win. For example, if player J has just turned in 3 bolds, and X is equal to 5, side stats could have: "Player J - 2 more spoils to win" which would note that, if player J turned in two more spoils bolded, they would win the game.
Or more simply, a column titled: spoils remaining
the numbers in that column represents [bold] spoils left to play until victory
Also, the spoils could be made public to all, a la the way teammates spoils can be shown during team games.
Obviously, If a player is eliminated, the killer gets the spoils. Additionally, if no one meets this objective, but they kill off the board, they clearly win.
How this will benefit the site and/or other comments:
I think it could create a totally new type of gameplay with entirely different strategies. Picture seeing that player A only needs one more card to play, they own it, and its nestled behind a 15 stack! Or, imagine the rush as you get a 3 card bolded set to win, surprising the rest of the field!
Or, picture making a kill on someone b/c you notice they have cards you own, and you kill them and can turn in in multiple sets, giving you the victory in one fell swoop!
It could have its own achievment medals, also.
Also, could create a unique dynamic for team games.
