Most of the Imperium does "respect" its "ancestors" in their own way, like Space marine dreadnoughts.I bet warhammer will be bigger in china than the US or UK. They fucking love warcraft/starcraft. They love loot boxes in vidya so much GW could replace regular sets with gacha style bullshit and make assloads of cash.
Its ghosts. No ghosts. really anything about disrespecting ancestors.
As for the Imperium, if they portray it as a totalitarian state and give all Tau a japanese accent, I bet China would love bashing them blueberries in.
