Hypnospace Outlaw. I'm not old enough to have been using the web in 1999, but I like to think it was exactly like this.
I got a ttrpg itch recently (unrelated to bg3) and started looking into pathfinder 2e and will probably pick up the core rulebook in the next few days.
Since you already said Tunic, I'll throw out Riven: The Sequel to Myst

I got sick of Hades. Everything that happened in the house before and after runs was great, it was just I shame I had to repeatedly slog through a run for half an hour to get new conversations. I came to the conclusion that roguelikes probably aren't for me.
I'm loving the MicroMacro: Crime City series. Not the sort of games you can play over and over again, but I love games where you have to use actually use deduction and logic to solve mysteries.
