Runescape (osrs/rs2) in my opinion is one of the best games ever made.
It’s janky, the mechanics are all dated in a pseudo 90s ADND RPG style, the game econony is carefully balanced to accommodate this through RWT and botting. There is a lot to dissuade someone from enjoying it.
But the quests, coming from a passion project by a small team are some of the best quests I have ever played. Custom mechanics have been written for a lot of them (further adding to jank), the writing shows its pulpy influence and revels in its own absurdity.
I have yet to play another game where I have helped a pirate union-bust his zombie workers for his rum operation, worked for the fairy mafioso and helped Jean Luc Picard with his hot air balloon in the same day.
I had to stop playing at points because I was in tears from laughing so hard and without guides some of the quests are genuinely challenging and stimulating.
Always a brief respite from the modern gaming community to revisit osrs
Personally I’d just boot into a live environment so the SSD isn’t in use, backup important things, then wipe windows partitions and resize /home to use the rest of the space on the disk
