Best multiplayer games of any genre that last for the next 100 years?

That's why I like to play multiplayer games because grinding is fun and ranking up also. You can build your character, inventory, rank or whatever. But when I played MWII grinding for camos I realized there's gonna be a new call of duty, potentially MWIII in November 2023 and this current MWII is gonna be obsolete. I also got bored of playing cs:go and guild wars 2 so I searched for the best old mmos and I came up with guild wars 2, oldschool runescape, Tibia, Ultima Outlands, and EverQuest Project 1999.

Now I peaked at all the games I just mentioned and I came to the conclusion that I don't want to click things in runescape for 99 stats so Project 1999 is indeed the best mmo ever made. It's just more fun than all the other mmos. I made a Barbarian Shaman and am level 5 and a friendly player ported me to Freeport. I just wanted to ask you guys, let's say I'm 26 years old and I want to spend my time on one or two games only and when I'm old I can still play those games.
