I liked the Spelljammer setting back in the 2e days. Never to really use it (or Planescape) but I bought a bunch of stuff for it that now sits on the top shelf of a closet behind other stuff, because that's how much gaming stuff there is in the Tenkar household (not counting gaming stuff in the basement or in storage).
Anyhow, I digress a bit, but the fact remains that I like bit's of space opera in my fantasy at times. CRAWLJAMMER is a zine that puts a little space opera in your DCC RPG.
Issue #1 of CRAWLJAMMER gives a taste of what's to come. Don't expect Traveller type detailing. It's flavor or crunch, which is just the way I like it.
Highlight for me? The Lizardman Mercenary, as it could fit into a standard DCC campaign with little if any tweaks. Really well done.
Issue #1 even includes a 1st level adventure: Cry Freedom and Let Slip the Bat-Men of Venus.
These two bits alone are well worth your three bucks.
I'd rate this up there with Crawl! It's the right size to sit next to my Crawl! collection too!
