Baseless assumption or not, you're still wrong. Braid is entirely derivative. It's Sands of Time meets Blinx meets Mario Bros. Blow has the temerity to lambast Japanese developers for having no ideas, yet he borrows all his ideas from French, Canadian and Japanese developed games. A slight case of do as I say, not as I do, no?
Super Meat Boy is not a good game. It's hard, its unbalanced, it has impossible jumps and exists for no other reason than to kick you in the balls repeatedly. Conversely, something like Bit.Trip Runner is hard but you can at least learn how to do it in the same vein as a traditional 2D sidescroller like Contra or Ghosts'n'Goblins.
My complaints don't have to do with the developers, especially in light of SMB where the developers themselves are actually by all accounts pretty likeable characters. I just strongly dislike their game. Braid was fine in the sense I finished it, but it's not at all original and it's nothing that I would entertain the thought of replaying, unlike something good as per Portal. It's just interesting, given its derivative nature, to see it stated as being incredibly important by its creator. It rings hollow. Or rather, it reeks of hypocrisy.
