I usually play with the sound muted so music would just add space. Though some of the better games it does work out nice, so probably depends on the quality of the production.
Sometimes it feels like animations end up taking most of the effort and the rest of an update is minimal at best. So i suppose it depends on the dev/team. Story or plot is where its at imho.
Star trek for what i hope the future is like at least one day. Looking at you next gen/ds9. Star wars for when a little fantasy needs to be thrown in. Like both though.
I'm not big on the horror genre in general. Though there was one zombie apocalypse game that was actually quite good but i cant recall the name offhand.
