Warhammer 40,000 - Shadow War: Armageddon seems to be a popular topic as of late. I was always a fan of Necromunda, the idea of a gang war in the Underhive was just so cool. The setting was such a different take on the epic scale conflicts that the rest of the 40K universe focuses on (if you can find them the novel series that came out with the last release of the game are really good).
That gang war idea was so appealing that I jumped into the now out of print Judge Dredd Miniature game as a replacement. It's a shame most of the models for that were so dated looking and focused on the early Dredd comics. The system was great to create whatever you wanted with the skill trees and seemed to do a decent job keeping a reign on one gang running away with it. Since this is now out of print I've been reading Rogue Stars which reminds me quite a bit of Rogue Trader with the focus more on a narrative play rather than a straight up beat down.
I'd love to have more of an opinion on the new Shadow War release but it sold out everywhere and I don't get a feel good feeling paying significantly more to get the terrain and rules separately. I'm hoping they reprint the box set with the updated book at some point. Honestly The only reason I pick up the GW box games is because they're such a value compared to buying the individual boxes. fingers crossed they listen to fans and bring it back like the "limited release" of Space Hulk that seems to come back around every Christmas. (I still need to get that one.)
