How about a little PS trivia, either single or multi player. A simple '/trivia' command in the chatbox, would allow players to play anywhere. This would encourage more people to actually read the settings and history of the PS world. A minimal reward of tria or a random item much like the looting system, increasing accordingly.
In the distant future.............. A gauntlet! In this land of heros, there must be a way (other than fighting) for one to prove him/herself. A test of bravery, skill and endurance. This could be made up of the typical devices one would see in a movie, like pendulems, rollers and the like.
