@Xenxs @Cotillion189 for a long time the setting was static. But a few years ago they released Dark Imperium, which advanced the storyline and modernized/codified some concepts, notably the Primaris space marines. Leviathan is the most recent release, and updates the overall narrative again. That could be a good start if you want to catch up on what’s current. Disclaimer: I’ve yet to read it
@Cotillion189 I always enjoyed the Inquisitor series by Dan Abnett. Usually pretty easy to find. My favorite fiction is Deathwing. It’s older, and not necessarily canonical with modern 40K. As far as games go, I thought Space Marine was pretty fun overall. Not too difficult, nor too easy. But there’s a lot of games out there, and I’ve not played most. Of course the miniatures are great. Opinion might vary on the games played with them, however
@Hrothgar59 @morras I have a whole box set that I want to paint eventually
