As promised, here are some additional photos of the Mars Needs Steam game, these from Phil Tortorici. Phil also loaned me the "Lost Martian City" (looking remarkably like an Afghan hill village) which featured prominently in the second and third games. Although it was built by another friend, Phil did a lot of additional work on it, making all of the roofs removable so figures can be placed inside the buildings. We see in this picture the American scientific party (with escort) entering the lost city. Phil took his pictures in sepia, which is a nice period effect.
Here is a more panoramic view of the Lost City. It was built in two parts and when put together covered about three feet by four and a half feet, with twisting rabbit-warren streets, overhanging balconies, all sorts of great stuff. It really was an impressive terrain piece and it helped further break up the table into lots of small clearings. That helps the feel of the game a great deal. The game tends to bog down if there are lots of open spaces -- who wants to start walking across an enormous open plain when the other gun has a field gun and a Maxim machine gun?
And here is a nice picture of the last turn of the final game. Just visible in the top center is the Bavarian overall leader, Count von Lager, replete in formal wear but still packing a revolver which he used to hold off a gaggle of Americans so his men could withdraw behind him. This was not long after the Bavarians had turned on the Prussians and mercilessly gunned down the Prussian naturalist Frau Bluecher. The Bavarians pushed deep into the city and snatched a number of artifacts almost from under the Americans' noses, and went on to win a convincing victory. Long live Bavaria!
