Well personally I like to get into the lore of games I play, so an interesting storyline is number one for me, however Doom is one of those games where you can’t go too in depth to the story when playing the main campaign, so they’ll need the perfect balance of story and ripping and tearing. What they did with codex entries was nothing short of genius. More glory kills would be awesome as well, maybe put multiple glory kills for a common direction so if you tend to glory kill from the same direction, you won’t be watching the same one over and over again
