He never said it would be free on Steam.
Then don't get it on Steam then....
I've gotten 2 games here free from Steam, and they are about 4 updates (if not more) behind Patreon/SS releases, even some of the ones I've bought are several updates behind.
There are hardly any "free" games on Steam (the ones that are, are a very small slice of the game, if not an outright demo) unless you count the "F2P" ones with a shitload of microstranactions...
He said the public version of his games would be free, that means on any platform, not just here.
And I can think of quite a few AVNs (some really good ones among them as well) that are still free, or were free from the longest time with a lot of content:
- College Bound Episode 1
- Lunar's Chosen (has a price now, but was free for at least two years or so)
- Come Home
- Motherless - Season 1
- No More Money - Season 1
- Welcome to Free Will - Episode 1-3
Just to name a few.
I will buy it on Steam when more content is available or the price will be lower, since it has something important that the version that's on here doesn't have: Steam Achievements.
