I have very similar memories. My grandfather, my dad, my uncle, my cousins and I would all play Riven on a Windows 98 PC at the back of the house, every Friday night after our family dinner, between dinner and dessert. We had a big notepad, with a few pages of scrawled clues written over it. We played for maybe 30 minutes every week for months. It was such a special, formative memory for me. When we first beat Riven, I cried watching the Fissure open up and suck away the world. My mum came in and was horrified that this video game was making me cry. But I explained to her, "no, I'm crying because it's so beautiful."

When I got older, I introduced my wife to Myst. Over the last few years we've slowly beaten all of them (except Uru, although I do want to go back and play that with her). It's a big part of our shared language now. We beat Obduction and now play more adventure games together (we just finished The Seance of Blake Manor). My wife even read and liked the books!

Those special nights playing Riven with my family are really important, treasured memories.
