I absolutely love the fact that new ideas on how to play and compete are being thought up for a game that is relatively old, and am happy that such thoughts and strategies are encouraged here. In addition, I really do love the way that competition is used here as a vehicle for improvement and learning. That said, I'll say what many of you are already thinking about one of the more recent suggestions.
In such an individual scoring system inside a randomized teaming mechanism, there will certainly arise instances where one's team losing the game would actually improve an individual's ranking. For example, when one of your teammates just pulled ahead of you in the rankings, especially in a case where you and they are far out of the 'pack', like first and second, doing the math may show the member in second that losing this game would put them back in first. Now, I would never suggest that someone here would intentionally and obviously throw the game, but I do wonder if it would be more difficult to trust such a player during their turnset, or misjudge a player's suggestions during discussion. And God forbid they do make a mistake, like forget to finish a chop and miss a wonder by 1 turn. I would be concerned how the likely ensuing conversation would affect future participation by all involved. Something to consider before implementing any individual scoring system in a team game such as this.
On the other hand, a draft seems more innocuous, and possibly more fun for someone like me who would like an opportunity to get to know more players... but...
Say there were a team created through random draft of members that knew each other well, had a high standard, and were more interested in high performance than allowing learning through mistakes. Not too hard to imagine, I think we had a team like that in game 20. Say also that someone like me, with little experience in SGOTM were assigned by random draft as the last player on that team. Should that team be required to spend twice as much time to explain everything to me (still pretending that I am basically worthless as a player, which is also not that hard to imagine), or are they allowed to play in a way that is fun to them and finish quickly? Of course no one would require a group of good players to 'dumb down' their team and have less fun just so that one of their group (who was assigned to them, and not chosen by them) could follow. Pretending I am also dense, it may take me a while to realize that my input is too elementary to be given serious thought and response, but it would eventually happen. I become a lurker. Not saying that lurkers don't get enjoyment (I sure have), but I am a handicapped lurker, in that I can only lurk one team. I become much less likely to offer to play in the next game, and all the knowledge and experience I gained through my 'exclusive lurking' is lost to SGOTMs, as well as one less body to be used as a turnplayer in the future. I realize this risk isn't 100% likely, but it is enough that it should be thought through and thoroughly examined before an unrestricted random draft is implemented.
Or, at least that is my opinion.
