Last Tuesday, a game about musical environments called Proteus arrived on PlayStation Vita and PlayStation 3.
The title was originally released on Steam earlier this year, but no Xbox 360 or Wii version was announced.
When asked why the game didn't make it to Xbox, creator Ed Key said "basically because Curve approached me and they already have a good relationship with Sony. And because Sony seem to do a way better job of building and maintaining those relationships with small studios and indies (for example, funding ports)."
While many developers release on most platforms to gain a higher profit, Key says he doesn't have to stress about maximizing sales. "I personally don't try to hit every platform, its just what opportunities arise. I guess it would sell more on additional platforms, but it would be offset when you include the costs of porting it and certification."
Proteus is available now on PC, PlayStation 3 and PlayStation Vita. You can check out a trailer of the audio discovery game below.
