Taverns and ale.
 

what would be really productive for a player is if he can grow hops and barley and things like that in order to use as ingredients to make beverages. water + hops + barley = beer or another beverage similar. The players could then collect all of this in a cascet (like a barrel with a tap in it) and then could put it in his house either to sell to players or to make himself a drink when he needs. this would also open doors to one of the first player run taverns, so we could have a tavern with cascets there, but the servents and barmaids there need to fill them up as well as serve them. Also, if you drink too much of this, it can make you slower, have less health, hiccaugh, lose health slowly every few minutes, and then wear off, as a signiture of being drunk. what do you think?

U played too much eq? =P
anyway i LOVE!!! this idea, should be easy to implement and add alot of fun ;)

edit: maybe it would increase our chances of getting this available if someone here would make the gfx for hops, barley and so on ;)
