In the debate over whether games are art, Braid gets one thing right. It allows itself to have this artsy, obscure and possibly pretentious premise because it has great gameplay to back it up. While mechanically not as tight as a dedicated platformer like Mario or Castlevania, Braid transcends genres and brings more ideas and great designs to the table than anything in recent memory.
Furthermore, the game has a wonderful unique look and sound that is just as refreshing as it is excellent. So while not everyone will 'get it' and it's heavy cerebral nature takes a certain frame of mind to be played, anyone after something different or something challenging should definitely check Braid out.
