The first time I played Riven was way back on the playstation. I still have my playstation disc. However I loved the game but did not care to change disc so offten on the playstation. So When I seen that GOG updated it for Windows vista and xp. Just so you guys know this works great on Windows 7 Professional with no issues. If you love puzzles and some interesting story line. The graphics are even better compared to the way it was on the playstation do to the fact when a video started you could see a outline of the video so this is major improvement. If anyone has the OLD DVD version and having issues with it not running any longer on there computer. Diffently buy this one from here you should have no issues with this version. Thanks for updating for later operating systems.
