Those are really the only two I've played, put I got the demo for realMYST. It was a good concept, but it just seemed overdone. I liked Riven better than Myst becuase it had better graphics, better puzzles, better music, almost everything was better. Except for the 5 discs, but that was fixed with the DVD.
I heard from many reviews that Myst III wasn't that great. It wasn't developed by Cyan and that's probably why. And also the prices fell from $49.95 to $19.99 pretty quick. A hit game like The Sims is still expensive.
