For me, 2D Mario games comprise my comfort series. Aside from the handheld entries of the New Super Mario Bros. series, I can play them dozens of times and still have fun even after a game's wealth of secrets is depleted. I think of the series as the ideal feel for platforming – even with great entries to the genre like Super Meat Boy and Rayman Legends, the play style found in Mario games still has my favorite "feel" to them within the genre.
