[Ragnarok]

Why not start a bracket similar to the NFL playoffs? You have X number of people on the hill currently. Take the number and devide it by 2 and then start two hills. Sort of like a East and West hill. The winners of their respect hill (either east or west (name can be changed)) will face one another in a match to win it all and be the best of both hills, until someone knocks them off.

One drawback that I see is when you go through the two hills again and the current king stays on top, suddenly you have 2 more plus the current king on the top. What to do in this situation I haven't thought of yet but given time I'm sure I can think of something.

Another way to do things is to start seasons. Create a schedule and each player has a set schedule in who they must play. The top X amount of teams make the playoffs and battle from there. Making it that much tougher to defend your title by the fact that you have to make it through another full season of games and then all the playoffs to make it. At the same time, you eliminate the chance of having just 1 game reuin your trip to the top. You can now rebound and still make a run at the title.

Yet another way is to create a system in which the computer ranks your wins and losses and strength of schedule and then the top two teams make it. You call it something like HCS (Hill Champion Series)....
Of course that was just a joke and I'm sure you all know what I refer to in those comments. (BCS Sucks)

Just some thoughts.
