The only Mario game that actually seems to have been a complete rehash was Super Mario Galaxy 2 and that game still had its merits. Saying Mario as a franchise only repeats the same concepts and ideas is fairly absurd. Each of the main console games save Galaxy 2 had new environments and gameplay elements. To complain about lack of "innovation" in Mario games when there is a large lack of so-called "innovation" in games today seems a little crazy. No problem in saying you don't like Mario games, but to say there's been nothing new for a long time doesn't hold much water with me.
