My best friend plays games all the time. He loves Everquest and still plays it to this day. On occasion, he will try a game that I tell him about, but he isn't really into hardcore/single player rpgs.
But sure, in general, there is still a bit of the feeling that you must be weird or geeky or autistic or whatever to play games as an adult. That feeling is still out there to a degree, but not nearly like it used to be. Gaming has become so popular nowadays, like phone games and video games, and all that, that gaming has come to be a much more accepted hobby, and has gone mainstream, even among adults.
That said, I'm sure there are still places and industries where people probably don't want to talk about that they are a gamer in certain workplace settings, for fear of being looked upon as strange or something.
More broadly speaking, I would ask the question, Why does it matter? Why do you care, in other words, what other people think of your hobby? Eventually you get to a point where what other people think isn't so very important anymore, like it was when you were young. I don't care what other people think about my hobbies, my politics, and so on. Why should I? I don't need the stress, lol
though I tease back, at his age I didn't google walkthroughs I stayed up all night and searched every last damn pixel.
