Easily the best time I ever had with Mario Kart 7. Most of the custom tracks are really well polished and quite impressive at times, with only a few stinkers among them (looking at you Star Slope and Space Road). The online is also solid and there are even some neat little features like the light on your 3DS flashing rainbow colors when you enter the last turn on any Rainbow Road or the Blooper item being an actual menace.
