Need a quest idea? Let the player, or better - many players - find some conflict to resolve. Some charachter or group on your server npcs has some problem, took something, or needs an item from another group, and they need you to get it and set things right.
The hard part is to make it so that your helping the group or npcs casues another upset someplace else, and to make it loop on and on so that the server will last indefinetly, since it is an online game. There should be no end to it, no grand finale. Its not Mario where you rescue the priinecss, game over; the father of the princess now dosent like you and becomes an enemy but the pricess and you are in love etc.
good luck!
