Dumb Question - License

Hi guys, so when I download the free UNITY programs, it says free for personal and commercial use. I don’t get it. Then I start the program and says 30 day free trial. Errrr. I don’t think I’d be able to learn this in 30 days. Can you guys get me straight and tell me how this works?

Do I:

get unlimited time to learning Unity via adding resources, assets and plug ins. Then buy a license when I am ready to sell???

The Unity editor won’t stop working when the 30 days are up, you can use it indefinitely. The 30 days is likely a trial of the pro-features.

Thanks a lot brah!
