Thing is though, hardly any of these creators have this as their full time job. Even with all the talk about how this creator is milking it... You don't make a living of 60 something patreons... So how long a game been on this site, and how much time the creator spent working on it, differs quite a lot. I'm not a Patreon, but if you look at Vega's patreon page you will see regular posting and updates. (updates that seems not always reaching this site).
I played through the recent version fresh. There is new things compared to the version from November 2020, because that was the last one I played as well.
