Vidyascape, a faithful recreation of the 2007 runescape experience.
All the quests are implemented and the xp rate is slightly higher than regular osrs.
It feels fun to re-experience this, and removing the pressure of a monthly subscription makes it much more enjoyable. They are running it since 2014 without any hiccups.

I feel the same about multiplayer games without gated progression and LAN server hosting. (Or local/splitscreen)
These days I can’t even play a multiplayer game with friends somewhere with shitty internet. And because of progression you have to force yourself to only play together, but never with different people or by yourself because then you will get ahead.
Yeah, I’ve seen so many games drawing inspiration (or even very closely copying) slay the spire. Just shows how good it really is.
