Yeah, there’s a heck of a lot of overlap between Traveller and 40k- they were developed around the same times (classic traveller was '77, Megatraveller was '86, Rogue Trader was '87 and then Traveller: The New Era was '92) so there’s a lot of cross-pollination between the two
After their efforts with 4e’s VTT, I’m not surprised they’re so happy to be able to show basic functionality
