In Weedcraft Inc, you aren't the only person selling marijuana to the citizens. There are other people wanting to get rich. They will systematically steal your customers until you get rid of them. Here are a few tips on how to deal with competition.
Click on the competition bar displayed at the bottom of the screen. The map will now display information about all competitors and their headquarters. Click on a building that got your attention to open another window. Here, you can learn about that competitor's influence and their goods.
Your competition can move out if you decrease their influence to zero or when you convince them to move out. To decrease their power, you need high-quality goods and sell it at a lower price than your competition. Your product's quality must be at least extraordinary. You also need to lower the price. When you do that, each transaction will lower the power of your competitors in a given area. Remember - even when someone moves out, it doesn't mean that you will always be alone in a given region. A new competitor will appear at some point.
You can interact with every competitor and build your relationship with them. This helps you when you want a favor. The higher your relationship, the greater the chance of succeeding. Favors can be used to achieve various goals. You can get access to new strains of marijuana at a lower cost. Even if you pay a bribe, this will cost you less than paying the standard price. The disadvantage is that you don't know which type of marijuana you will get. You can use favors to cooperate with other competitors or to tell them to back out of the business.
