Attacked not really, made fun off, yes.
In the 90s early 2000's people didn't get why I held on to old video games, I used to find them I lot more at garage sales and people treated old games like most treat VHS today. My Dad never understood my passion, he always thought that video games where a waste of time and a waste of money. People back them never understood why I held on to all my games.
Nowadays when I say I'm a video game collector most people just think I have a hand full of games and If I show them I picture of my collection they usually have a look of surprise and want to see it them selves. They ask "Do you have a Nintendo? Atari? Sega?" etc..
The closest I get to being "attacked" is once in a while at a garage sale I'll mention I'm a collector they treat me like a reseller and won't work with me on prices or just give me some sarcastic remark because they got ten other guys before me asking about video games.
Then there's the resellers them selves who push me, lie to me, say nasty things to me because they look at me as taking their profit away.
But funny thing is most of the time when I show pic's of my collection to people (even those who never played a game in their life) they think it's awesome. I have even gone to a garage sale or a game store, show them pic's of my vast collection and they start bringing out stuff and are generous about price because they see it will go to a good home. There's a local game store I visit that the owner will save odd gaming stuff that comes in and offers it to me first at a price below what he'd normally sell it for just because he wants it to go to someone who will love and appreciate it.
