We've been testing out some ideas for scenery and terrain to use in an upcoming Rogue Trader rpg campaign. As with our Pathfinder and The One Ring campaigns, we'd like to supplement the traditional pen and paper rpg experience with miniatures and terrain, especially during combat. The concept was to make modular boards that could represent the interior of a giant spaceship, or any other interior location we might need for the grim dark sci-fi setting. So far we have four 12"x12" pieces that can join to form a 2' square. This will be expanded to nine pieces, allowing a 3'x3' board with some 16"x20" pieces to accommodate larger spaces if necessary. We've been experimenting with a variety of surface textures that while are visually interesting, don't interfere with placement of the miniatures. So far so good.
