People adapted to Mario and Zelda without Miyamoto as well
But... Mario literally became Sonic after Galaxy 2. Other than Odyssey, I personally can't think of a massively game-changing Mario game since then, besides Maker, but that's not really a mainline Mario game (IMO). I mean...
SMB - Saved the gaming industry
Lost Levels - More of the same, fair play.
SMB2 - Tried something really different to the gameplay we already had. New artstyle, too.
SMB3 - Improved on original formula, added lots of new content, critically received positively. Again, a new artstyle.
SMW - Introduced a few new mechanics, but mostly added more. Brand new artstyle.
SMW2 - Rethought the mechanics of SMW, and pushed the limits of hardware. New, and gorgeous, artstyle.
SM64 - Introduced a whole new dimension.
SMS - Added brand new mechanics, tried stuff that had never been done before in Mario. Really nice design.
SMG - Incredible innovation once again.
SMG2 - More of the same, but with the same approach, and still very popular.
SMO - Incredible innovation, once more.
Meanwhile, we got,
NSMB - A fresh new outlook on the game's roots - good all round!
NSMBW - A bigger experience of the same, still well liked.
NSMB2 - Was coins the only thing you could do here? I mean... it's got a few new things, I suppose? Same artstyle, though.
NSMBU - Uhh... chief, did we just release the game again?
3DW - It's this game again, but in 3d. Cat Rosalina, I guess, so the whole game is original?
I don't like where this is going... Mario seems to be going in the same direction as Sonic in a sense... Mario is becoming more of a marketing tool than an innovative game series. It... it kinda hurts.
