I'm confused by the names you rattle off as "just straightforward additional characters." You mention "the faceless, the hoarder, the maestro d', the restless, the touchstone" - wait, what restless? Is this an early name for one of the playbooks? It just really piqued my curiosity.
I love all the material that's new to me, namely the space marine mammal, the supplemental walkingsuit rules, the large-scale weapons and harm rules, and oh boy, the Macaluso. I was expecting the Space Marine Mammal, and I knew there would be an additional playbook- I had no idea... holy shit, a fucking hivemind! Your playbooks are never boring, and now they're beyond interesting. I was excited about the SMM, but the Macaluso blew me away.
I felt like there was something else I wanted to say, but I can't think of what it is anymore. Oh well, maybe later.
