I can't describe how excited I am to see this game on here at a price this low. I swear gog.com or Cyan or Ubisoft aren't paying me. I really just love this game (and all Myst games). I played this when I was about 13 so I couldn't really connect the entire story fully. I'm very excited to get back into the game and try again.
Riven is one of those games that stays with you. It's so immersive that in your mind it becomes a place memory rather than a time memory. You actually think you've been there, or at least I feel that way. It takes me back!
This game is probably one of the best video games to exist, in my humble opinion. Years later the graphics are still striking and the in-game real actor sequences and monologues still put games like Mass Effect and Oblivion to shame. And that's not even mentioning the plot! Please buy this game. It will not disappoint you (although it might make you pull your hair out in frustration!).
