With over 100,000 apps to weed through in the App Store, developers need to find some way to appeal to the masses; a hook or a gimmick, if you will. There's no shame in it, but they've got to do something to get you to check out their latest downloadable title, and one of the absolute best ways of attracting potential purchasers is by preying on their sense of nostalgia. If you yearn for a simpler, easier time, without all the hassles of the modern-day world, and you think it's best to live that out on your high-end, touch-enabled smart phone, then these apps are for you.
