Than he will collect experiences and some coins when they will finish quest.
I dont like that idea. Coins would mean a whole money system which would suck and no quests. It shouldnt be about collecting coins. And no kind of experince either becoase then it would be some kind of a level system and that would be quite pointless.
You will be able to for examlpe collect herbsd his own house etc.
I never liked the idea with having a house.
I think it would be best to have no goal at all. Leveling up, become rich and have the best house.
It should be about creating levels and play them online, unlike your original idea my idea is unlimited.
What would be more fun in the length?
