Ranking

A game can be played as Free game or a Ranked game.

Free games does not affect ranking but the outcome is stored as statistics.

Ranked games distributes Ranking points among the involved players.

Initial implementation of ranking
Score list based on VP in ranked games that fade over time. I.e. recent games give the VP's and older games will only give parts of it.

= Some ideas - NOT implemented =

Ranking points

 * All players start at 0 points
 * A player with 0 points is a "newbie"
 * Each game provides 1 point in summary.
 * A game with a newbie gives 1 point to the winner: +1, 0
 * A game with no newbies give 3 points to the winner and removes 1 point from the looser: +3,-1
 * (Idea) Point distribution in a 4-player game: +3,+1,-1,-2
 * A player may only play ranked games with those within some (10?) points difference or the 10 players above/below in the ranking list? (Note: A high ranked player shall NOT be able to play against newbies. See "Cheat" handling below.)


 * If you don't have any active games and don't respond to challanges you may loos a point. OR Loosing a point per month if you have not played any ranked games in the last month is simple and working.

"Cheat" handling for ranking
A high ranked players may not play games with low ranked/newbies to prevent him/her from gaining by creating multiple accounts and have very simple wins.

4-player game: If two players cooperate, then the other two may cooperate too. If 3 players cooperate, then 1 will be sad. Is this a problem? Nah, it is up to involved the players in the game if they choose to cooperate and I think the rumor will spread and no other players will play 4-player games with them. Note: Cooperation could be non-attacking & non-stealing agreements (not handled by the game but by the players themselves).
