It's genuinely amazing to me how well Riven holds up, especially compared to other games in the genre from that era.
I watched a playthrough of it again recently and it is incredibly how much detail they were able to put into an early game. And I love the use of live action for the characters in the earlier games too. Which they utterly ruined in the most recent Myst remake 
FWIW they patched in an option to switch to FMV so it's good again, but I believe the upcoming Riven remake is going to use 3D models for people and keep the voice acting of the original actors. I understand why they have to do that but I'm still not thrilled. Remake looks good otherwise though
