Three days of Arcade Expo madness went down this weekend at the Triple Crown Pavilion. All games were on free play providing non-stop action for gamers. The Expo included tournaments of classics like “Sonic The Hedgehog” and “Super Smash Bros.” The exhibitions featured retro gaming systems arranged with detailed info cards — most were playable. Local Joshua McClellan enjoyed his Saturday at the expo, “I really liked the museum, and the game boy camera photo booth was genius.”
