I'm sure but if you want to market your game well, you should include a gif or link to said live steam on your sales page. People often make a decision within 3-6s on a page. Without a animated demonstration, your chances go down signifigantly.
It's not a game, it's just a weapon reskin pack for another Doom mod. What you see there is pretty much what the addon adds: Just visual reskins. I don't see a need to add video for this project.
Now for the other projects I've added, I've included trailers with video, but it's not necessary here.
