The time has come where I am bookmarking funds, planning assets and organizing the business model for my first game.
For those of you who have successfully released and funded your game on Patreon etc. What steps did you take on the business end?
Form an LLC? Trademark your title?
I want to remain reasonably anonymous, how is this achieved?
When hiring developers, do you require NDA?
Thank you for any insight.
