What Maverick said pretty much covers it. All the most of the redid Mario games actually end up adding a lot from the games before it aside from Mario Brothers 2 (Lost Levels) and Super Mario World. (Yoshi was the biggest add there. Took away the invetory of Mario 3.)
The Mario "off" franchises do a lot to spice up and change around the normal versions of that kind of video game Mario Kart, look how many people made ripoff kart games!, Mario Strikers, spices up soccer etc..
Mario Party's don't add much except changing the minigames but it's not like you can do much to the intereactive boardgame-minigame market.
