So, I'm reading through Black Crusade, and yeah, the rules are a massive improvement on Dark Heresy et al, so, now, I want to run a Dark Heresy-style loyalist game using these rules.
How to do this? Hmm.
First: Use a mix of Dark Heresy Corruption with Black Crusade's. Use Insanity. Also; use something like 'Status' instead of 'Infamy'.
Second: Remove God-based alignments. (Treat all as 'Allied' for XP costs.)
Third: Come up with archetypes, similar to Apostate, Psyker, Renegade and Heretek.
Four: Minor details, such as adding in more Imperium flavoured talents (Chem Geld, Pure Faith etc), whilst restricting the Chaos ones.
Boom, that should be it. A mid-to-high level loyalist game, where the players play an Imperial Guard command squad, an Inquisitorial retinue, an Arbites suppression team, Administratum tithe inspectors or whatever.
Some help with steps 3 and 4 would be nice!
