Is it normal that i get "jumpy" when i play video games?

Haha I'm the exact same! Although I do that in real life as well.

I don't think I'll ever forgive my friend for making me play one of his stupid zombie games with him. I was an actual mess playing it, and my character spent most of the game running away and being eaten. It wasn't pleasant. At all.

Don't know if it's normal, but it's definitely fun to watch.

RESIDENT EVIL on playstation in your big ass dark basement with the surround sound on max. . . . EPIC!!!!
lol

Maybe you should play some Amnesia: The dark descent to desensitize yourself

*SPOILER ALERT*

I remember when I was playing Aliens vs. Predator, I was starting the marine campaign...in the 1st level the motion sensor went off and scared me a bit...but it was just a box...then I go and open the door and an Alien jumps out at me and I freak the **** out lol good times

My arms move around a lot when I'm playing certain games, but my butt stays glued to my seat. :P
