Gamecity Hamburg utilized the 2021 digital iteration of Gamescom to showcase the regional gaming ecosystem, specifically highlighting the work of local independent studios. The primary objective was to provide a platform for Hamburg-based developers to gain international exposure through the Indie Arena Booth Online, a digital exhibition space produced by the Hamburg-based firm Super Crowd Entertainment.

The initiative featured five specific indie studios—Tiny Roar, Mooneye Studios, OneManOnMars, Radioactive Dreams, and Klickaffen—which were selected through the "Road to gamescom 2021" program. These developers presented a variety of projects, ranging from the world premiere of the sci-fi adventure XEL to the mobile casual game Unbuild. Beyond the shared booth, the regional presence included additional Hamburg-based entities such as ROCKFISH Games, Curvature Games, and Daedalic Entertainment, as well as extensive streaming coverage provided by Rocket Beans TV.

The scope of this engagement focused on the Hamburg games industry during the August 2021 event period. By leveraging both the Indie Arena Booth and various Twitch and YouTube streaming programs, the initiative aimed to bridge the gap between local talent and a global audience. The methodology relied on curated selection processes and institutional support, including prototype funding and incubator programs, to ensure that regional developers were prepared for the high-visibility environment of the world’s largest games fair.
