Was thinking mainly on the criminal aspect so cops have a reason to snoop around and can catch a property owner out whilst conducting an illegal production. We already have the weapons which is really nice love it, definitely inspired by that here are some ideas I've heard and thought of and feel free to add your own.
We should start being able to stock items we have crafted in businesses, eg. mashed potatoes stored in your business can be bought by players in /pricelist for a specified amount.
Weed:
Skilled crafters say lvl 10+ can make edibles out of their weed which heals you and gets you high, which could be sold in cafe's or to other players and the BM dealer
We could also bring in crafting of hydroponic setups to set up in homes/businesses which could be a pot object requiring you to /plantseeds & requiring /water every half hour for 2 hours giving you a decent yield(that's getting a bit intricate though)
Speed:
Can be crafted by crafters lvl 20+ using pseudoephedrine could make it have similar effects on you as meth just brainstorming but there's another possible drug with what we already have in the server
Cocaine(been my random idea for a long time):
Using a plane preferrably, head to a secret location far out to sea guided by your gps(island i would map) to /pick coca leaves, returning home, using 1 unit of fuel from a jerry can at a crafting table you /craft 1 cocaine which uses 2 coca leaves and 1 unit of fuel to produce 2 to 4 grams of cocaine which have a very high selling price.
/wear-ables:
I propose that using items which can be farmed (wool) (cotton possibly & possible use for gold & more) most of the /wearable items become objects players can craft and sell to other players creating loads of RP business for pawn shops and clothing stores.
Just brainstorming for the most part but appreciate any additions to this and feedback
