The game works well for me on Windows 10. One caveat is that each time the game is launched, it claims it can't restore my save. However, if I mouse to the top of the screen and reveal the "File" menu, I can manually load the save and start my game from where I last saved it. As for the game itself, I am greatly humbled by the atmosphere the game is able to create. Despite its age (no pun intended), Riven transports me to a whole new world, captivating me with tidbits of Atrus' tale and keeping me in the moment by incorporating the puzzles directly into the environment. However, incorporating the puzzles into the environment also begets my biggest disappointment with the game - sometimes, I'll miss a small detail and get stuck. Since the world is so large, I end up island hopping, looking for what I missed (thank goodness the game no longer spans five discs!), clicking on all the items I see, hoping they'll spark an insight I didn't have before. It turns out the thing I missed is usually a small environmental detail right where I got stuck -- what do you mean there's a switch there!? Argh! This frustration will sometimes break my immersion but yet I have no regrets from visiting Riven.
