I took over the writing for ICSTOR when he needed someone to write for Taboo Request. I was paid $250 for the writing in that short game after it released.
I then did the writing for MILF's Villa, and was paid $500-$1000 for each update that I wrote for after I had completed the work. When it came to Milfy City I was paid after each update was released.
During periods of time when there is no work, I don't get paid. I have no pension, sick leave, annual leave etc. I file a self-assessment tax return every year with the HMRC.
A few months ago I posted on here announcing when I had started taking on more roles for ICSTOR in addition to writing the game's dialogue. For example: Running a job competition for new 3D artists, negotiating with Patreon about their Trust and Safety guidleines, writing first drafts of character plots, some project management stuff etc.
I have not been paid anything for Milfy City 1.0, and I won't be paid anything until the game releases.
