DOS Thursday 007: Prince of Persia

This is one game that is really something else. You will be dying over and over and over. There is a lot of trial and error and you will be using all your skills to get through this game. Not only that, you have a timer in which you need to beat the game or else you will not be able to get the good ending. It's an amazing experience from start to finish and definitely started a genre of its own. Things that came later on like Tomb Raider and Blackthorne used similar gameplay and it shows.
