Other than concept on RISK: Factions, my main duties were designing the map-boards that the game is played on. They had to be themed per faction which was a really interesting challenge, to create that diversity within the unity that is the aesthetic of the entire game. We referenced all sorts of old-world maps and textures to come up with fun colors and a unique playablility within the game.
It was sort of an ironic twist in my work history. Previous to going freelance with concept and illustration, before working at EA, I made maps for the USDA. Actual real maps for use by the Forest Service! Now people are using them to plot world conquest.
