One of the most exciting things about going on a trip, whether you’re going out of the country or exploring a new state entirely, is packing things you like to do to occupy your time on a flight, in the waiting area, or in the car. As someone who travels often for vacation, my must-bring items for any trip are a book, my iPod, my journal, and my portable handheld game system. It’s almost guaranteed you’ll make the time go faster if you bring your 3DS or PS Vita, while waiting to get to your final destination. I do think there may be times when you might not feel up to investing too much time on the game you’ve brought and want something much simpler and requires less focus. This is where app games become your solution.
