Only a suggestion, how about an extra game option for r/t players. Just an extra option for an r/t game in which the only difference been is that if the player doesn't start their turn within 5mins of the player before them, finishing theirs, they will be kicked from the game, their territories converted to nuetral and points deducted. This would be an excellent anti-deadbeat tool and also would be much appreciated by the rt junkie's.
This of course would be slighlty different in a freestlye r/t, as the 5mins rule could only come into effect for the final player of each round, taking their go. When the time runs out any player having not played a turn, are again kicked from the game, their territories converted to nuetral and points deducted.
The points deducted should be a set amount, say 100points for example, just enough to stop players just quitting because they are not going to win, as they would only loose a fraction of that playing the game to the death, like any true r/t junkie would.
