Braid creator Jonathan Blow working on RPG

In a lengthy (and interesting) interview with Gamasutra, Braid creator Jonathan Blow revealed that he's currently working on a new 2D RPG. Blow divulged few details about the project, though he mentioned making the dialog system closely tie in with the core mechanic of the game, saying, "what goes on in those dialogs is actually very closely related to the core mechanic that you do in the RPG." Exactly what that means and what the core mechanic is, Blow isn't saying. Don't get too attached to the idea of a Jonathan Blow developed RPG though, as he said that he's toyed with several ideas since finishing Braid, noting, "You never know. Next month, it could be a Pac-Man clone or something."
