DuneMud has been going since 1992.
Ultima Online is still active. Came out in 1997.
There are probably a few MUDs older than that still active, but I don’t know any myself. I don’t THINK Materia Magica is older but I honestly don’t know when it started.
Edit: MM started in 1995. Wow.
MUDs were my first thought. Haven’t logged into one since probably ‘94-‘95. Actually met a few friends on there.
StarCraft 1
diablo2,warcraft3 had enough constantly new custom maps to entertain fans for years.
The Realm Online, 1996
Eve Online since 2003
Yeah, same for me. My oldest character is 2006 but I mainly just do trading and see how high I can stack isk these days.
TF2: it will be 19th this year!
runescape , that game my bro played that you only use words. SC1, WC3. i played wc3 up until '18. sc2 is already 16 years old, HOTS, and LOV is about 10 years already. maybe OG DIABLO 2.
Second Life is about to celebrate its 23rd Birthday.
My offering: SubSpace (now SubSpace Continuum), 1997 - https://en.wikipedia.org/wiki/SubSpace_(video_game)
I’m sure there’s gotta be some MUD still running on a forgotten mainframe.
Feel like Tibia would fit here
I think Nexus TK is still going
