GAME: Pokemon (Game Boy, 1998)
When Pokemon debuted, we had the time of our lives collecting, confining, and pitting helpless animals against each other. But there was always that nagging feeling that lingered wherever we went. We’d hop on our bike and make it to Route 66, then BAM! Our childhood frenemy stepped right in front of us and did nothing but taunt us and send his overpowered pocket monsters at us. And just when you thought you had him beat for the last time, he’d rear his ugly head once again. Oh, and the final boss? Guess who? Enough already!
