Strategy games.
You collect gems at every turn. From those gems, you start building assets. You start with the smaller assets, and then they help you get the bigger ones.
Most freelancers end up focusing only on collecting gems at every turn. The successful ones build assets.
The 3 assets most relevant to freelancers are brand, permission and expertise. Brand is the promise they are making to the people they seek to serve. Permission is the opportunity to connect with them consistently. And expertise helps them in keeping the promise over time.
Without all three, you are running a hustle. With them, you start building a business.
