I know some other game making programs require you to have a certain license if you intend to sell a game made with it such as construct2 a simple free one but if you were just a group of friends that wanted to sell a cheap $5 game you needed a $120 license for each person. Does unity do this as well sense there licences cost hundreds of dollars we want to know before we start anything ?
You can sell with the free license with no restrictions, unless you made >$100K in the previous year, in which case you need to buy Pro.

Ok thank you so much one more thing does unity have a option to allow multiple people to work on the same game at the same time and actually see the changes being made ?
