Allow me to expand a bit on my 40K Skaven vision. The most important part is that they're not Skaven. GW already loves to tease the idea with the Hrud, but even with that, a underfoot civilization of schemers just doesn't work on a galaxy spanning scale. Or at least I don't believe so. My answer instead is that my ratmen would be another minor alien civilization like the Zoat, Squats, or Tau, confined to a little region of space where they raise Hell, but are otherwise unknown.
How this came about is a meandering tale. Originally, I just wanted to use the Skaven models for something. Looking around the online store for more ideas, I found the
Forest Goblin Spider Riders. Arachnid riding ratman raiders. Perfect. But then I though, what am I to do with all the goblin models? And the paucity of guns?
The brainstorm of an Alien Empire struck, and suddenly it all made sense. My Ratmen would be the rules of a multi-species collective. Thoroughly evil of course. Basically, the ethos of the Skaven, but 40K compatible. This opened up more modeling options, such as using
Dwarf Thunderers and the new line of plastic 40K Grots as sources of more guns. Just a little remodeling to make them alien enough - I was thinking of turning the Dwarves' braided beards into fanning tentacles. And because three races didn't seem Empire-y enough, I'd throw in some Skinks for more numbers. And plenty of other odds and ends for special stuff, like Ork vehicle bits for a ramshackle look. All in all, a monstrous mountain of modeling, but a beautiful symmetry of ethic and production.
Obviously, I'd love to have some special rules to reflect their unique composition. But I'm still staunchly opposed to making up my own ruleset for them, not least I alone would be willing to play with it. And it's not like I don't have enough game design on the brain already. When I first came up with the idea, the
Eye of Terror book and it's
Lost and Damned section was still a legit armylist, and I had planned on using that. I briefly considered using the Eldar as a ruleset (fast and flimsy), but the new Guard Codex would work great. Grey Seer for a Primaris Psyker, plenty of conscripts and heavy weapon squads, Doomwheel Hellhounds, Warpcannon artillery, and a gussed up Assassin for a Sly Marbo stand in. If only I had the will.
