I would very much like an official star conflict sticker series. Of the logo, faction insignia, and maybe some ships and stuff.
Shirts and other merch would be a nice addition to your income as well because not only do you get paid for it, but you get free advertising too.
I would especially love another one of those black and red shirts that you sent out as rewards for that contest ages ago. It’s so nice but since it’s not in production I’m almost afraid to wear it for fear of damaging it.
