BoardGameGeek has created an upgraded start player marker for Terraforming Mars! The base of the rover figure measures just under 2.5" in diameter, so it's a very nice size with good detail for those who are into painting their minis! Or, for those who don't, it still looks great on the table!
The mini was cast by DUST Miniatures, with the base, wheels, and sensor in ABS plastic, and the main body and camera arm in PVC.
