Since many problems of holding events
seem to have to do with the question whether
there should be prizes or not here my opinion:
I think there should be special prizes for
winning events, not really money.
Winners of big events could get a special
trophy or hat. Winners of kingdom games
or ctf or so could come on a team-screenshot
that is put on the wall of the kingdoms game
/ctf building. Things like that. Something
that is a good reward but don't make other
people mad because of the prize being too
high or because of cheating or so.
