Hi! Those are all games where the renders are made within DAZ. Those are totally fine to sell on Steam and GOG. But you won't find games like Eternum or Ripples on those platforms (which use similar or the same engine as I do), if you do, please tell me :D
So for now, the only way to support is through Patreon/SubscribeStar/Ko-Fi/Itch.
The +1 is from me, I usually give a thumbs up :)
