I won't insult anybody who has fun with video games because it's a hobby like music and movies.
On the other hand if someone, in society, is bragging about finishing Dark Souls in SL1 or any other "hard" tasks in video games, I am pretty sure many normal people (well, people not used to video games outside of the mainstream news or mobile ones) would see that person as a weirdly obsessed adult that doesn't always take a shower.
Somebody who won a sport competition or had helped science would be socially seen as a better person fundamentally speaking.
PS: It pains me to admit but people trying hard to make video games a "legitimate art form" (by making hours long analysis about Zelda or pseudo deep indie games) are making me loathe them more than people who just sees them as a hobby or entertainment.
