OK....
"The Coreline Multi-Verse Depot:
A Multitude of Munitions for Murder, Mayhem, Mischief and More!"
With a name like that, it doesn't just sounds like an "equipment catalog" book, but should also have a location (or sample location, I guess that this is a pretty big sales venture so we are talking just one store), sample characters (with a name like that... what do you guys say? Some guy that is a combination between Willy Wonka and Burt Gummer?) and sample adventure that would have the players go trigger-happy.
The cover doesn't feels like it should be an ACME box anymore. More like one of those late-night TV ads of crazy salesmen, with the psychodelic colors and all.
BTW, nice to see you, AnimeSniper. Been a while.
