Highly recommend you pick up Space Marine II. It just got some new content, and pretty much all of it is glorious. If you do decide to play it, scope out the Astartes Overhaul on Nexus Mods. Takes an already epic game to legendary heights.
And for what it’s worth, I don’t blame you for leaving. Thinking I might be out of here when my sub runs out. Played since vanilla, done pretty much everything there is to do in the game, and honestly? Yeah, I hate the direction it’s gone.
