Oh, I love the advert with the grandma. "Hey kids, would you like some Shambler liver pie?"

Indeed, Doom has a major sci-fi theme that often overshadows the Hellish/demonic motifs. In Quake, it's all about darkness and medieval/gothic evil. Even the hi-tech base levels have a pretty rough atmosphere and feel far away from the recognizeable "normal" world (if it even exists).

Heretic/Hexen relies on depicting heavily corrupted/conquered worlds, littered with decrepit buildings and old dried-up corpses. You play the role of a bitter survivor, thrudging through the ashes of your once-glorious homeland and looking for revenge...

And Wolfenstein focuses on the mythological aspect of WW2 - superweapons, unnatural experiments, secret societies, the occult, man-made monsters, etc.

It's good to have a variety of themes to play :)
