I could have done with a bit more crossover into Attenborough territory with the commentary: "Carnifex pups learn to cleanly eviscerate their prey by watching their mothers. Here a mewling pup still has its victim's leg hanging from its razor sharp maw."
I recall the game play of 40K being tedious and boring, and with wildly unbalanced factions based on the whichever developer publishing new rules for the guys they had a hardon for, but I still do like the lore.
