BY FRANKLIN: Have you ever walked into a game store and noticed that they stock a retro version and re-release of the same title?  I am sure most adult gamers have encountered this situation at some point, which then creates a dilemma: which version should you buy?  Sure, the original retro version would be pretty awesome from a nostalgia perspective, but sometimes you just want to play a classic game on a modern console with improved graphics and features.
