8 minutes ago, skotothalamos said:before they did mats, they advertised a box of four 18"x18" boards (made from boardgame chipboard, I think) to push together to make an X-Wing play area. It did not survive playtesting because of how easy it was to knock everything around. I'll try to find the link.
I'm just saying, their first attempts at play areas are not always good.
