Crafting
Missions
Rewards
Let me explain. If i m somekind of armorsmith, making armors, suits etc for fighters, i would love to create my own mission, post it on a public board, asking a gamer to go kill some npc's (because i need somekind of specific loot from them ) for an hour.
During this hour, the items i m looking for (items i previously selected when setting up the mission ) that the gamer is finding will automaticly goes to me; when on the other hand at the end of the mission i will give a reward to him such as an armor ( depending on the difficulty of the mission, reward should be bigger or smaller )
it comes down to do somekind of trades, but with a mission point of view, where people using this system would get a bit more experiences because they contribute to helping each other in game.
This concept would create a new type of system, the gamers will organize the missions themself...
