I picked up Hyde St but haven't cracked into it yet. I can't wait for Moltar! The best producer a Space Ghost could ask for! Unfortunately they may need a new band leader but I have a feeling we'll see him again.
The only flaw I'm seeing in Ghost Machine is that it's not clear how all this is a shared universe.
Redcoat and Junkyard Joe are effectively immortal, so crossing them over with Geiger or Rook should be doable, but I don't see how Geiger and Rook themselves are related.
Hyde Street definitely also feels like it's own thing.
Yeah I've really only been following Geiger tbh, idk. Just couldn't get into the other two, and haven't read Junkyard Joe. Hyde St though, I like horror, so we'll see!
Was a 6 page backup in Geiger #6 I think? Boy scout helping a little old lady across the street, but it turned out she poisoned her family so the scout does her in Spectre style.
