German games firm Kalypso Media has increased its stake in developer Realmforge.

The company previously owned 60 per cent of the studio, but in a post on its website, it revealed that it has snapped up the remaining 40 per cent of shares. There's no word on how much this set back the publisher.

This is because Kalypso wants Realmforge to take over development on the Tropico series. The firm has also invested in the studio and has relocated the outfit to a larger office in Munich.

“The expansion and complete takeover of the shares is a logical consequence of our strategy to expand our own development resources not only in Germany but internationally," Kalypso managing partner Simon Hellwig (pictured) said.

"We are offering the highly qualified, motivated team in Munich the opportunity to focus exclusively on the further development of exciting franchises such as Tropico, Dungeons and Spacebase Startopia in the future."

Realmforge creative director Christian Wolfertstetter added: “Developing complex city-builder and strategy games with that special x-factor element, that are well-received within the community and the wider market on all platforms – that’s something we do well. The Tropico brand is therefore a perfect fit for us."

The two companies have worked together for more than ten years, with Realmforge historically looking after the Dungeons strategy series. The studio's next title is Spacebase Startopia, which is set to launch in early 2021.
