We can make some competitions for players to enter but they need to pay, for example you need to pay 200 coins to enter and you need to give me 1 bronze battleaxe,1 bronze 2H sword,1 mithril axe and the prize will be a adamant 2H in a hours time and the first person who give it to me will win the prize. Make it only one prize but if someone else comes with the items after the first person take it any way but make the first person get the prize.
