gibbeynator: Well, Presto has been looking for a way to get the Journeyman Project games on Steam. It's probably that.
Crosmando: Wait what, Valve wouldn't let the JP games on Steam?! With all the shovelware crap and broken games that get sold on it these days they wouldn't let some actually good adventures on their service?
Who knows, Valve is really weird with how they handle releases on Steam. For example they refused Paranautical Activity from initially getting on their service when they were going to be published by Adult Swim because Valve stated "they didn't want devs thinking they can bypass Greenlight by getting a publisher" but still allowing devs to do just that. Not to mention all the cases of them turning down games again and again only to change their mind after a set amount of time like Space, Pirates and Zombies which was turned down consistently for a year then out of nowhere they were accepted.
Now I'm not trying to start a Steam bash here, I'm just saying that Valve when it comes to how releases work on Steam are odd and often nonsensical.
