I was so excited to receive this! Setting up and putting away Terraforming Mars used to take so long with all the bags of pieces. Now we just set out these inserts, and we're ready to go! If you're a Terraforming Mars fan, do yourself a favor and get this and the Boardgame Boost overlays with backboards. You won't regret it.
Thank you SO much for the kind words and for your patience! I'm SO happy you enjoy it!
