The developer behind Murdered: Soul Suspect, Quantum Conundrum and Dark Void has closed its doors. http://www.bit-tech.net/news/gaming/2014/07/03/murdered-soul-suspect-developer-closes-down/1
"The game received a mixed to negative critical reception thanks to poor combat mechanics and clunky dialogue" And because they made a real stinker of a game lol.
So, do developers go bust because they made a poor game, or do they make a poor game because they're going bust? . Also, Crytek next?
How many of the games listed have you actually heard of? DerpBike anyone? That's the reason why they've gone under.
Good developers face going under on a regular basis, so it comes as little surprise that a mediocre one has bit the dust. I feel for them though
