1. Reliability rating exists on one of the forks (vdip) so the code has already been done.
I'm not sure what the plan is regarding integration.
2. Standard practice *should* be to cancel a game with a '01 nmr (they're not counted for Ghost-rating, and i believe games can auto-cancel, but i'm not sure if this happens on vdip) - though i would also put forward the opposite point of view.
3. this has not been tried.
4. it is easy to find games which have countries in Civil Disorder (on the games listing), but since they are often weakened by two consecutive turns of no movement they are often lost causes... Or they are weak 1/2-center powers whose players have given up. I thought there was a points discount for taking over, but i'm not sure.
5. Auto-pausing would be nice.
As a catch all solution, i'd prefer to see a games-master added to each game (ie the creator) who doesn't have to play, but has the power to pause, or kick players (basically all the mod powers currently coded, but limited to that game) This would allow cancellations, pauses, and solve more problems than it causes.
However the basic issue remain, if you don't know your game-master and he does something you think is shite then you'll be unhappy.
Similarly to resolve the CD issue, i think playing people whom you know to be reliable (from getting to know them in tournaments, or on the forums - judging by their Ghost-rating etc.)
CDing is here a much smaller problem than i suspect is is on the facebook version of this site... but i'm not sure that's saying much.
Lastly, my *rant - in the case of a '01 CD, you are forced to re-evaluate your position, suddenly some players have a huge advantage and you can use diplomacy to counter this. It is an unbalanced game, but diplomacy is by it's very nature. This does not have to ruin a game, but can be seen as a challenge.
I put this view forward only as an alternative, i think we all prefer to play the game we signed up for rather than the one we are left with.
the Best solution i can think of is restricting your play to private games where you have talked before hand to the players and pm'd them the password. (even a password on a public thread is useful as it means the person read the thread...) I never play unpassworded games (who knows who might join?)
