The "issue" with upgrading to a single business license is that other peoples are not allowed to use it, unless the license is used/attributed to a single computer that everyone using C2 in the team uses.
If you're having a worldwide spread team, a single business license isn't the correct way to go.
Any person using C2 to make the profitable game you're aiming for has to have a license, and if the games makes more than 5000$, all need a business version.
