40k definitely stands out against other sci-fi settings. The superficial stuff is obviously the cyber-gothic aesthetics and semi medieval power armour, but I reckon the recism/xenophobia that the setting is mired in is just as appealing the people as the space marines clunking around. Or rather, they go hand in hand.
Consider the other major sci-fi settings that a kid/teenager is offered today-Mass Effect, Star Wars, Star Trek and a whole lot other ones show conflict between humanity and alien races and bad and solvable by simply talking things over. In 40k you simply get handed a power sword and get told to kill everything that's not like you.
Do you guys reckon that it's an appealing part of the backstory? It definitely forms the core of the fluff ("In the grim darkness of the future, there's only war"), where there's no compromise, no misunderstandings and it's ok to hate other beings who in any other situation are just as sentient, rational and mature as you are.
