 * Newbs' ratings should be considered "unstable".  A stability point is needed: at least 20 matches against at least 4 opponents to be considered "stable".
 * The maximum rating movement should be 5 in either direction per match.  This will occur when: 1) the opponent is "stable"; 2) the opponent's rating is at least 25 away in the target direction.
-* We are slightly concerned about the devious, talented player who will become "stable" with zero wins, then prey upon the high-rated players to quickly bring down their 98+ ratings.  However, the establishment of a "revert match" option should be included with the system, and such unusual activity rebuked and the player's account removed.

13 total games.

== Overall ratings ==
* Not fair to directly compare an XvT-only player with a JA-only player. They have no way of directly competing. Make individual game ladders be the focus for these types of people.
* For the unusually versatile, suggest an "overall" ladder that adds up every rating the person has earned. This goes hand-in-hand with the "Renaissance" category of awards. Participation in all 13 games is almost mandatory to have a chance at 1st place, due to the automatic +50 pts boost from a new game. A score for someone with only 1 match in all 13 games would be around 650.
* The "overall" ladder will not be emphasized - not placed as the #1 ladder. Suggest placing the most active ladder as the most prominent. Also have a permanent order, by genre.

== Game ratings ==
* Suggest the range is 0-100, with decimal points. Display 2 points on ladder, store up to ~6.
* 0 and 100 should never be achievable - to do so would let someone stop playing entirely and never be beaten.
** OR, these ratings are achievable, but reset after a given interval (when months change?); that way people can claim to have reached "perfection". This would be a rare case, as we would make it very difficult to achieve rock bottom or top.
* All newbs start off with the rating of 50.
* Wins move rating towards 100. Ties move rating towards 50. Losses move rating towards 0.
* Newbs' ratings should be considered "unstable". A stability point is needed: at least 20 matches against at least 4 opponents to be considered "stable".
* The maximum rating movement should be 5 in either direction per match. This will occur when: 1) the opponent is "stable"; 2) the opponent's rating is at least 25 away in the target direction.
