Of course you can still play the Lepanto.
Just a slight variation, same end result however. =D
And yes, I just realized that a points system would not differentiate between an unreliable player and a new player. But the point system works on the individual player, and not on the game creator. The purpose, is to deter players from being unreliable, it is not to allow users to create games and discriminate between other players.
If you have a higher score, you should not be playing someone with a much lower score than you, because either they are more unreliable, they are newer, or they are not as skilled. That is the only discrimination, and while it means that perhaps new players might have to deal with unreliable players, hopefully, the point system and a competitive atmosphere would deter players from being unreliable, and instead focus on playing the game with the intention of raising one's score.
I would not penalize consecutive NMR's more than isolated incidents, because if it's consecutive, it is likely that the player has taken a break due to real life issues, or vacation, in which case, they should not be penalized harshly, because obviously real life comes before phpDiplomacy. The other possibility is that the player has quit phpDiplomacy, in which case, further penalization would have no real effect, and might in fact be a major discouragement to any second thoughts the quitter might have.
A multiplicative effect on NMR's is large enough, there is no need for exponential growth.
