Even back in the day Descent was more of a niche game. I played a crap ton of it on the Kali ladder as well as modem death match with a buddy, but we were the only ones out of our extended friend group that liked it vs everyone that was into doom, quake, etc. A lot of people got motion sickness issues from it and couldn't really do anything about that.

If you're interested in Myst style games but want to play a modern spiritual successor, check out The Witness. It's an astoundingly well designed game, though some of the last puzzles will take some persistence.
