I'm not a huge fan of Mario, but honestly, what Nintendo fan HASN'T played a Mario game? The only games I've played really extensively are Super Mario Sunshine and Superstar Saga, though I also own New Super Mario Bros. for DS and got a decent way through that. And I have spin offs like DDR: Mario Mix, Mario Party 6 and DS, Mario Kart Double Dash and Wii. And I also own several Mario games on my 3DS that I barely touched thanks to the Ambassador Program, including the first game.
