After this post someone noted I was unlikely to get any use out of the two Warhammer boxed sets and asked if I wanted to trade. Which I did. I traded them in for DCC RPG and ACKS . . .
. . . the person I traded with also very kindly threw in DCC 65.5 Doom of the Savage Kings. Which was very cool of him.
I'd already got the ACKS pdf and liked its version of B/X enough to jump in on the Companion Kickstarter. DCC RPG I knew a little about, but hadn't really taken it in.
It's a big old tome, but I wizzed through in a couple of days and am absolutely smitten. I love it. It's currently my favourite version of 'the game' and I can't wait to play it. No doubt there'll be more DCC RPG posts along the line.
