Does everyone has 1 game that we cannot let it go?

I mean for example "Trickster", 2D MMORPG.

I played it first time almost 10 years ago, I quited, game closed.
Anyways, there ware someprivate servers running, I played it again then quited (4-5 times with official server and private).

Back and forth.

Now I'm playing it again and still like it tho :D

minecraft, played it every few months for like 2 weeks for several years

Runescape for me. I have played the game on and off for like 15 years now. I don't think I'll truly quit until they shut it down.

I play through SAn Andreas atleast once a year.

GTA san andreas, I still play the online roleplay servers
