License to work in a team

Hello! :grinning:
Being currently a student, I would like to develop an MMORPG game. But two questions block me.

  1. Can I use a free license to develop an MMORPG game with one or more friends?
  2. Can I also market/publish it once my project is successful?

Thank you for your answers.

PS: I hope I am posting to the right places on the forum.

I do not represent Epic, but yes, and yes. Business partners can be tricky.
I suggest reading the eula and faq Frequently Asked Questions - Unreal Engine - Unreal Engine
Your answers are there, and the rest is good to know.
