As someone outside the fandom looking in it seems like the entire 40K franchise revolves around the Space Marines, with the other factions taking a supporting role at best.
Space Marines sell the most, so they get the most frequent support. Each faction has a very loyal and very ravenous fanbase though. Generally if someone is a “space marine fan” they’re either really new, or extremely old. It’s the people that are into the Imperium factions as a whole you should look out for.
Tbf that’s only the imperium fans. The rest at least know they’re playing pretend. Maybe not the Boyz I think they’re serious.
