#8 Super Smash Bros Melee
For the best multi player game on the purple cube we have a an accident of a game that struck something within a set of gamers that played it and never stopped. This game and the stories told around it from the fantastic Smash Brothers documentary to the more recent e-sport reports of late. There was a time where we had a small community in my small home town that each Monday met at a small runed down warehouse turned leisure farm and played Melee. The speed and explosivity and chaos of the game combined with the unique almost sandbox like play each person could bring.
I still play smash, but I do not play melee. But I still watch high quality tournaments of this game. The masters of this game are wizards with a controller. And the impact this game has had on me is present in the friends and frenemies I made and the ridiculous wombo-combos of the best players who picked it up. Now if switch 2 gets gamecube games as part of nintendo online and make this officially playable online it will get a resurge I'm sure. Imo Melee will be around longer than Ultimate - even if the later probably is a better game over all.
