"No Material" emblems or maybe... "I eat, sleep, S--- BeamNG" for a shirt design or hat. maybe just the BeamNG Node logo for a coffee mug or on some sleep pants. Likely not the craziest suggestions you heard.
Yeeesss, this. I need a mug for work, a BeamNG one would totally do it. BeamNG stickers would also be cool.
I actually had the idea of a Covet badge for my old Swift. So it would definitely be cool, I would buy them! (It's in the junkyard now tho, F)
