I usually play games muted or turn most of the sound off in the settings. Absolutely always turn the music off. I can fill in the sounds in my brain so the rest is kinda unnecessary.
3D games are what I prefer. The visuals and story are overall usually better for me than in the comics, it's usually hard for me to find just the right comic.
Any music by John Williams and John Carpenter (always great suspense, think Halloween, The Thing, and The Fog). The music in the new Star Trek movies is also pretty great.
I very much prefer normal body proportions. Anything unnaturally large just doesn't do it for me, although I know lots of people look for those things in games.
I'm going to go against the grain and say I like when they are hairy in games. Although most don't do a good job of making it at least somewhat realistic looking.
