I'm in my late 20s - I know there were people who hid that they were gamers when I was younger, but I was never one of them.
I openly admitted I was a gamer, and didn't care if people thought I was a nerd or geek or whatever other insult they could come up with. I was introduced to gaming by a teenaged friend of the family before I started school - we played on his Sega Master System, and occasionally my parents let him take me out to the arcade (if they'd tagged along, they never would have let me play Mortal Kombat games when I was 10).
