Truly classic game. If you grew up playing Pokemon, don't hesitate to pick up a copy of Pokemon Red or Blue and a GameBoy Color (they can be found pretty cheap used, or just go to your attic and get yours out). Sure you can emulate these games on your phone now, but the experience just isn't the same. The actual Nintendo hardware will provide you with an overwhelming onset of nostalgia, and you'll feel just as if you were a kid again.
