I dont think I ever beat Riven. Got rid of it, wont work right on Win2k. Exile. Took me 3 days the first time. The puzzels can be realy realy hard, like the last one, but they dont take to long to do. I think they should have kept the puzzles just like they are, just had more of them. Myst IV is said to be more like Riven, all takes place in one world, with minor trips to others. Unlike Exile that has 5 worlds, all of which play major rolls.
