For years, the debate between Unity Personal and Unity Pro has been a rite of passage for game developers. When your indie project starts gaining traction—or when your startup hires its third employee—the "Made with Unity" splash screen and the revenue cap of $200,000 become very real barriers.
For the solo hobbyist, Unity Personal is more than enough. But the moment you treat game development as a business, the Pro license becomes mandatory. The removal of the runtime fee (for Pro users) and the stability of Unity 6 make the $2,040/year price tag a reasonable operational expense.
You value your time over your money. The support, dark skin, and license server are efficiency tools. Skip it if: You are still prototyping or have not crossed the $100k revenue mark.
