I'm the exact opposite. Seeing gore in games pleasures me to no end.
Pleasure? Not messed up at all.
I am definitely desensitized by gore and other stuff like that. I remember last year I saw a really brutal beating of this gay guy in some third world country which ended in him getting set on fire, and I could not sleep. I was shaking and I was on the verge of tears but that stuff doesn't really bother me anymore.
I am pretty fine with gore, but I sometimes feel a little uncomfortable when I play God of War, and Kratos pokes a poor man's eyes out and rips off his head.
Most of the time, though, gore in a video game does not bother me.
Gore in real life is a little different. I do not enjoy seeing people in real life lose a limb.
It keeps you alive.
Blood, decapitation, realistic wounds, are fine.
Blood all over your body IRL would make most people die right there.
I'm not saying i HATE blood, i mean, i'm ok with a bit.
Like swiping someone with a knife in a shooter or seeing blood drips.
Hell, in RL i lose blood all the time.
I just can't resist games that are made of guys saying "Omg guys, let's make a game with lots 'o blood OVERKILL STYLE!"
