Video-gaming isn't just an ordinary hobby for Melissa Kaylor. In fact, it's a ginormous obsession for the 25-year-old Tempe resident, who spends practically all her waking hours either wielding a control pad or engaging in gaming-related pursuits in many different forms. As her alter ego, Mel the Office Gamer girl, Kaylor produces a YouTube series profiling obscure old-school titles, crafts cutesy plastic "pixel art" of iconic characters like Yoshi and Sonic the Hedgehog, and blogs about the gaming scene in the Valley. And in the past year alone, Kaylor has also helped organize a Nintendo-related art show at Bookmans in Mesa and participated in a nationwide 24-hour gaming marathon last fall to help raise money for the Children's Miracle Network. So devoted is Kaylor to gaming that she managed to keep up her playing habits even after suffering a fractured pinky last year. Now that's hardcore.
