alright, I just re-read, and X had suggested a complete collusion.. which as i stated before is highly illogical.. I was reading more into the guy with a backwards name

I don't see how a player controlling the orders of another player would work.

I think the landlock and meta-bonuses situation described are problems, but they are rare, and I don't see how the current situation is fairer than the one I described.

X, you can already view another players orders mid-game.. when booted it could be designated a player to take over for them, or the idea for them to be AI with modifiable via the view orders screen... the main problem I could see with another player taking over is if that other player is eliminated.. it could either stall games, or make the taken over player effectively worthless..

The order list panel only lets you change the orders moves are made in, or delete moves, so that wouldn't work.
Another problem is that in large maps in real-time games, having to move for two players could put you over the time limit.
I don't understand the final point you made, or who you were adressing.

A variation on allowing one of the remaining teammates to take over the booted player's territories could be a random division of the booted player's territories among the remaining teammates, if teams are >2.

No, you would lose all the bonuses of the booted player, and it would be a mess.
Unless you mean it would be done by bonuses ... I don't know if that's possible. That would solve the meta-bonus problem at least.

Of course, still the most elegant solution would be to re-announce the game on the open games tab and allow a substitue human player to take over for the booted player.
