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!
fucking nightmare fuel of mods 18 years ago…lol
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.
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.
Second Life is about to celebrate its 23rd Birthday.
Feel like Tibia would fit here
I think Nexus TK is still going
