I've noticed a few posts about a new game on Steem, 'Drug Wars'. It looks pretty interesting. You can build a drug empire and then stake your drugs for Steem rewards. Upgrading facilities can either be done for free(but time needs to elapse between upgrades) or if you are just wanting to become the biggest drug lord on the block you can purchase your upgrades using Steem (through Steemconnect).
If you are keen to give it a go, you can use my referral link below.
