Hello! We already tried to put our game on Steam. We didn't manage to release it there, we already had a page with a trailer and everything, but we were rejected at the last moment. We were informed that our game was not suitable for Steam.
Some advice. To increase your chances of passing GOG's curation, you (or the users) should create a GOG Dreamlist page. However to create a GOG Dreamlist page, your game must first exist on IGDB.com. So please create an entry on IGDB, so it could then sync with GOG's Dreamlist, so we could create a page and vote for the game.
STEAM/Valve seems to be of multiple minds on AVNs these days. Not just 2 minds... I mean it when I said Multiple Minds. They just plain cannot keep a straight line of thought on the content of these games much less standardize their offerings to match it. SO. Do not be surprised if in 6 months you find more games with far more not so clear characters in it for sale there.
