Same when we went through myst as well, the masterpiece one, not the new one.
Despite the limitations though, riven had an absurd amount of "views" or screens to give you the feeling that you were there. When I revisited it, I was afraid after the full 3d version, the kids and I wouldn't adapt to the still frames, but they held up surprisingly well!
I'm not sure how to help, but so much of that game is interlinked with itself, where few things are standalone. It took a while for us to get through it.
Surprisingly, people say the gauntlet at the end is the hardest part, but we got through it pretty painless. It was some door that we missed as we ran through the world's that tripped us up and needed to get a spoiler to continue.
