After dozens of plays of Terraforming Mars, we decided that the standard setup needed more variety. Over the course of three years, one pandemic, and hundreds of additional plays, we created a fully customizable experience – nearly infinite permutations of maps, milestones and awards, and global parameter bonuses.

This website details those design processes, shares downloadable Print-and-Play versions of our fan-made expansions, and also contains links for you to order your own copies of our "final prototypes" from The Game Crafter.

Printable Versions

We highly recommend the tactile feel of the punchout versions available from The Game Crafter above. We love ours! But if you want to DIY it, we're making printable versions available as we can.
