21 – Super Smash Bros 64
I know, I know, first Yoshi’s Story, now SSB64 23 steps over SSBWiiU, but my list is highly based in my personal experience (trying to do an objective list would be unfair, since I haven’t played enough a lot of master pieces, so I prefer to do a highly subjective one), and SSB64 is the version I’ve had best moments with.
Although the number of characters is low for today standards, and it doesn’t have so much game modes, I enjoyed it’s single player immensely: I prefer it’s story mode to the WiiU one, and the platforming sections were entertaining. Also, I hadn’t have contact with some of the Nintendo characters that appeared in the game (like Ness and Samus), and discovering them was awesome, while the ones I already knew were all very charismatic.
And multiplayer battles were addictive. I spent hundreds of hours playing with 4 players with friends, and we continued doing so many years after the game had released. The game is accessible but versatile enough to keep deepening on it, and those are, in my opinion, the keys to a great couch multiplayer.
