LB: I've always said that if you're going to release a remake / remaster, you should ALWAYS include a playable version of the game in its original form. The Halo remasters have been fabulous for this, allowing you to switch at any time during the game. The Monkey Island and Day Of The Tentacle remasters do as well. Can't think of any other examples off the top of my head, which goes to show it should be a more common practice!
