This game is great, but there is DRM still in the game. Best to get the game on a steep discount to see if the games DRM allows your computer to run it or not. GOG hasn't removed the DRM after several years of selling this game. The DRM checks your computer when you try to launch the Prince Of Persia game either from the exe file or from GOG Galaxy. The DRM looks for compatible hardware and if it thinks your hardware isn't compatible, it won't let you try to launch the game. It seems to work better on Intel computers. I wish this DRM didn't exist, but I'm happy I get to enjoy a great game for now. Maybe GOG will remove the remaining DRM in the future if possible or a mod will fix the game.
