There are many games on the Steam platform that can be quite expensive. Especially if you add DLC for skins, characters, and stages, the amount you need to spend might reach thousands of euro.But what is the price you need to pay if you are looking for Steam's most expensive single, standalone game? Well, one of the newest games available on the platform, The Hidden and Unknown goes for a whooping 1.949,09€! No, your eyes are not deceiving you.The game was developed by ProX, a person or studio (we are not sure) famous for bringing you...eh...The Hidden and Unknown. That's it. That is the only game they have ever released on Steam.We haven't played the game (obviously), but there are some walkthroughs on YouTube about it, in which the game seems like your typical, simplistic text-based adventure. Add to that the fact that the opening screen features a statement absolutely not supportive of gender equality, and you have an uncanny specimen of a game trying to be marketed as a philosophical experience. No, we don't know what they were thinking.Anyway, if you ever decide to buy and play this game, let us know how it went. Because we won't.
