The web-only license (including itch.io) has the royalty rate reversed: 25 to us, you keep 75.
Yes, you could have a Hobby Project thread for that.
This would be good for someone that wants to publish something that we consider too offensive for HG, for example. But you wouldn’t be able to have a thread here for a game we find grossly offensive.
You could also get a full-suite license, with mobile and Steam code, but that’s like a $20k Advance against 25% royalties.
