The original Mario Bros arcade game (1983) was the last video game I got obsessively into before puberty ravaged my brain and I suddenly lost all interest in video games and Star Wars action figures in favor of punk rock and dem tiddies. I was vaguely aware of the existence of Super Mario Bros 1-3 but I knew nothing about them, or any other video game from 1984 to 1990. After I finished college I bought a SNES to kick start a line of credit. I had no intention of getting back into games, but all it took was few minutes of Super Mario World. After playing through two or three levels, I knew what I wanted to do with the rest of my life. 2D Mario is the reason I am still a gamer today.
But ever since Super Mario 64, 2D Mario can kick rocks as far as I'm concerned. I believe in evolution, and the shit definitely evolved. I admit it can be fun to dick around with a NSMB game for a few minutes/levels once in a while, but they just can't hold my attention. They're throwbacks, and I'm just not into throwbacks. I 100%'d SMW (world) multiple times in its day. I 100%'d SM64 multiple times. I 100%'d Sunshine, Galaxy 1 & 2 and Odyssey multiple times. But the NSMB games, Super Luigi, Wonder... collectively I've probably played them all for maybe three hours tops.
[Super Mario 3D Land and 3D World are weird in-between games for me... I 100%'d each of them once and never felt like touching them again]
