There's one downloadable game that's been the talk of everyone in the industry lately:
PixelJunk Eden Braid. Unfortunately, PS3 owners are currently unable to try the XBLA game that has gripped so many gamers. The puzzle-platform game has been praised by critics for its innovative and satisfying puzzles which involve the manipulation of time.
According to GameFocus, Braid may arrive on PSN later on, once a timed exclusivity contract with Microsoft is finished. Johnathan Blow, developer of the game, also added that while a PSN version is possible, a WiiWare version is not, due to the system's limited memory resources. Hopefully, with enough fanfare from PS3 owners, we'll be able to see Braid on our system in the not-too-distant future.
