Only War Core Rulebook
Deciding to look back at the Warhammer 40k tabletop RPGs whose mechanics ended up adapted to Rogue Trader, the choice of Imperial Guard RPG Only War was not exactly a hard decision. Since that army has been my absolute favorite faction by a parsec from the moment I found out about the franchise, I was eager to see how playing them in a character game as opposed to a wargame worked out.
You can practically see the writers trying desperately to make the experience both true to the Guard’s limitations and playable/fun. I trust I don’t need to go into that much detail that an individual guardsman, even an elite one, is at or near the absolute bottom of the galactic food chain. There’s also the reason why Twilight 2000 was set in a scramble rather than in a war-their life is a very regimented existence with little chance for straying beyond orders.
Thankfully, the solutions are fun and interesting. Characters are part of a beginning chosen/created regiment that has set base gear and characteristics. NPC “comrades” are present to act as additional laser sponges-I mean, partners in war. More can be achieved, but only at the cost of chancing the logistics system (as unreliable and risky as it sounds). The regimental system itself allows for everyone from Tempestus Scion commandos to primitive worlders with swords and animal hides.
So yes, I recommend Only War to anyone who wants to be real serious and face the grim darkness of the far future without the need for power armor or super-enhancements.
