Calling all game developers in the Baltimore region: now’s your chance to have (potentially) tens of thousands of people learn about your next great video game.

Gamescape, the video game showcase for game enthusiasts and exhibiting companies alike, is back for its fourth year at Artscape, the annual summer festival that takes over Mount Vernon, Bolton Hill, Midtown and, as of last year, Station North. It’s routinely billed as the country’s largest free arts and music festival with attendance upwards of 350,000.

Game designers and developers: Apply to exhibit at Gamescape.

Organized by Ben Walsh, the founder and owner of Highlandtown-based Pure Bang Games, the three-day event is meant to shine a spotlight on not only the history of the gaming industry in the Baltimore region, but also on the small- and mid-size gaming studios at work today.

As Walsh told Technically Baltimore at last year’s Gamescape, “We hope to inspire people that walk through that [video game development] is a career option, that this is in their backyard.”

Indeed, as Walsh asserts, the gaming industry is in Baltimore’s backyard. Despite the office closings of Zynga East and Impossible Studios this year, smaller companies like Mindgrub Technologies continue to lead the charge into mobile gaming, making Gamescape a ripe opportunity especially for indie studios interesting in drumming up awareness of forthcoming releases.

Also, new this year is the Gamescape Market, where vendors can sell game-related merchandise. While it’s branded with the name, it’s a “separate component” to the exhibition itself, said Walsh in an e-mail. Vendors must pay for tables, which will be located outside the main exhibitors’ space.

Vendors, apply here.
