Super Smash Bros. Melee
GameCube / HAL Laboratory / 2001
I've tried playing this game a few times, and somehow it just never clicked for me - maybe because I mostly tried playing alone against high-level CPUs and always got destroyed, which doesn't usually happen in other titles in this franchise. Super Smash Bros. Melee is probably the only game on this entire list that I haven't played much of, but I just can't help but respect and love it for how much entertainment I've had watching it. As much as I can't have that much fun with it myself, I recognize that this is a fantastic game and the competitive scene is incredible - watching those high speed matches is always amazing.
