Another problem might be the endless donsig vs. DaveShack debates
What are you talking abut. Our debates draw crowds. How long has it been since we had a two page discussion thread in this game?
I agree they're quite entertaining, I think they've covered a lot of the important points that we'll need to sort out for the next DG, I'm not sure where I fall on most of the issues though, I've only experienced this DG, so I'm likely to vote for choices which are a bit different from what we've seen from this one.
Rules which are so detailed they are likely to be broken / Rules so vague they are meaningless
I'd tend to favor more vague rules. I think that would be the best system given an active judiciary which factors intent and impact heavily into their rulings. One thing I'll want to try in the next DG is taking a seat on the bench, likely a boring job, but it's probably one of the most important ones when a crisis does arise.
Rules which mandate specific time frames for action or inaction / Not enough time to allowed to make decisions, not even knowing how much time there is to decide, possibly missing out on contributing to a decision because a person is not on-line for two days
We need to have a minimum time before a play session can start, so that there can be discussion and then a relatively precise start time(+/- 2 hours) for the play session posted by the DP well in advance. If people running discussions and polls know well enough in advance when the decision is due by there shouldn't be sticky situations like we saw this game.
Playing vanilla when most activity is on expansions / Excluding those without newer versions from participating
I'm definitely going to vote for a vanilla version when this comes up everyone who has a version of civ 4 can play a vanilla game, if the population available is a primary concern we don't want to knock out a good portion of the interested players right off the bat by making them incapable of viewing the save.
Players who care more about their favorite issue than they do about the health of the overall game / People who ignore other people's favorite issue and drive them from the game
I know we had at least one new player this game who was very interested in map making and naming geographic features, while it was certainly necessary to explain to him how the DG worked, I wish this had been gone about in a better way so as not to create a hostile environment, having a favorite issue isn't a bad thing.
More focus on whether a rule is technically broken or not, than focus on whether the end result was damaging or not / More focus on playing a perfect Civ game than a good democracy game
I think we need to set up some sort of system so that there are metagame reasons for making bad, or at least unconventional moves in game. That will give us more choices to make for each turn, do we vote for the smart thing in game, or the thing which will help us in the metagame. This should increase how interesting the game is by making it more active, preventing us from becoming a hegemon in game, and hopefully with a larger number of controversial decisions to make we'll learn a more civil manner of making them.
Rules which require specific people to do certain actions
We definitely need to get rid of rules like that, at the start of this game I was interested in naming cities, but was thrown off by a law requiring the chieftain to head that process. Thankfully Methos was a very wise chieftain and this didn't become a major stumbling block for the game. Last month the elections didn't happen because the chieftain was required to post the election polls, there were at least three citizens who noticed the delay and did nothing to correct it because of the law in place (myself included

).
