I spend some time to make a custom insert for Terraforming Mars, I just dislike all those tiny baggies! Everything fits neatly into the box and I just love the boxes for the Gold, Silver and Copper resources. Its so satisfying to align them all inside :D. I also enjoy that the cards are at an angle, makes shuffling unnecessary because you can just pick a card at random. Really happy how these came out.
And this is what it looks like all inside the box
The inserts look like they’d move around a lot inside the box if you were to move it.
Things can move a bit, I did shake the box with everything inside, nothing came loose or was damaged afterwards. I rarely shake my games a lot so this would be secondary for me. It also still leaves some room for expansions if I want to add them.
It has expansions!?!
There are a couple, we only own one
From a Google ther appear to be at least 4!
