We should have a kind-of riddle tournament. We go in-game and solve a riddle. We get a location from that riddle with another riddle on a paper or something. Then finally you have to kill something and you get Xp,cash, and a special emote or costume.
We should have a marathon day. You start at one end of the map and walk/run (no teleporting) to the other end. the person that gets there fastest wins.
I think you should make like a Christmas party type thing. Where you go through a house looking for items which you bring back to a npc and you get rewarded. Say like if the npc tells you to get uh... 60 dragon bones you'll get rewarded with a item like a rune (g) set or something like that what isn't to expensive and not that rare
