(I dont't really like the word gamer and I'm sure many of you don't like it aswell, but let's play along with it for this scenario)
(Also predispose that the people in question are born in similar social conditions, adding this here before a cocky bastard tries to point that out and turn this around)
How much control do you really think we have upon the things we like, is it really our choice to like something ? Because I don't think it is, person a may be interested in videogames while person b may not even care about them. And do you really think that if conditions require person ''b'' to suddenly play videogames he will like them as much as person ''a'' who was naturally attracted to gaming ? Even if person ''b'' would be reborn into a place where he is surrounded by videogames and gamers there is nothing saying that he will like videogames as much as the people around him do, he may get acquainted with the mechanics and the genral sense of it but that's it.
I made this thread because of an anecdotal scenario, where my friends were trying to get another friend to play videogames with them, when he obviously couldn't care less about them. I thought it was the stupidest thing ever, obviously if he would have even a sliver of interest in games he would have shown interest in them before.
