"Treefrog Games is now the name for the company that used to be called Warfrog Games. The name change also marks a change in direction. Designs will be reprinted depending on the level of demand. There will still be limited edition versions of some of our future releases."
The Treefrog name and logo first appeared when Martin announced a subscription model for all-wooden games produced in limited numbers. These were published by Warfrog games under the Treefrog Line with the Treefrog Line logo on the spine and Warfrog's relegated to the back of the box. The first game was Tinners' Trail, the rest are listed here: Treefrog Line
The first release with a Treefrog Games logo was the expansion Steam Barons, co-published with Mayfair games, and the first new game was Age of Industry.
