Spar Tournament
This idea is for an automatic spar tournament that registers players via grabbing a blackboard or whatever. The tournament registers about 18 people. And, there could be custom tournaments too, but that's another idea.
Every time you win a match, you win gralats. Or the game counts your wins and pays you all at the same time depending on number of wins. The winnings would be the same for every win; a flat rate. So say player wins one match. He gains 40 gralats. Player wins 3 matches. He gains 120 gralats. 40 X number of wins. This would be fair, even for those with better skills and weapons. This way it's fun for learners and veterans.
Winners
The winner of the spar tournament would simply receive double gralats of the matches he or she won. and maybe there could be a statue to the winner or a title. Just throwing out ideas.
Additional Comments
Each tournament in general is turn based per arena. If you didn't register, you have to wait for the next tournament. Or go to another arena.
Hope you guys like the idea!
