Besides buying out all the DRG cosmetic packs because I'm a whore for coffee stain and ghost ship, the best DLC cosmetic I've ever bought is the dumb piglet Saltzpyre wears on his head in Vermintide 2. It's got a little wiggly butt and floppy Lil legs and it's adorable. Best $5 I've ever spent.
As a fellow whore for coffee stainI kinda wish coffee stain had something similar for Satisfactory (but I'm also glad there isn't) , but since they don't I took to buying the game 9 times (gifted them to friends) and bought merch over the years. It's so refreshing to have such insanely good communication between the devs and the community.
Honestly never got into satisfactory (besides watching silly runs on youtube) but I absolutely fell in love with goat Sim. Nothing beats that damned goat when it comes to a happy, silly reset for the burnt out gamer.
