Actually, this is a very astute obervation. Let us refer to it as the 'Mario Party factor'.
I've barely played my consoles this year. Last year, in the student halls, we played Mario Golf, Mario Kart, F-Zero and all the rest almost constantly. The three guys I live with this year have a passing interest in consoles (well, except one guy with the misfortune of owning a playstation), and as a result I fire up the N64 perhaps twice a month for a few quick laps around Mute City.
You know, I had to flog my Cube the other day. Pained me something rotten, but I'd barely played it (I had Luig's Mansion, Rogue Leader and Resi) and I need instant cash. Thing was I really wanted Zelda and Metroid... bah

Now then,

Show me a PC RPG that's better than Zelda. Or a racer that's better than Mariokart. Or a platform game that's better than Marioworld.
