Basement is a drug-dealing strategy/simulation game where you play as a great scientist that has been forced to do not exactly legal stuff underground, as nobody wants to support his scientific ideas.
The game is all about management. You build your own enterprise producing several types of drugs. Find the right place, build production rooms, hire workers and security staff, avoid the feds and build the most effective company.
You start small in a tiny basement, selling directly to a queue of buyers. Since the police have no interest in small-time dealers, you has some room to grow.
Once expansion begins, you will begin to fill trucks with your produce. This will allow you to sell higher quantities but be you will encounter fights if you get busted by cops or gangs. As you grow your empire will begin to become more fragile.
