"You like video games, hence you are lame" sounds like the battle-cry of those who find no meaning in life apart from cutting down the enjoyment of others. In other words, the kind of people whose opinions don't matter.
Is it lame to play Chess, Backgammon, Poker, Blackjack, or Risk? Clearly games themselves aren't "lame" and shouldn't be outgrown. What makes video games so different?
And who do you think designs these video games, anyway? You don't go very far in this business by age 23. A person needs to play and enjoy video games in order to make better video games for the next generation.
For Statistical Data:
I've been part of a group of game enthusiasts since college; we met once a week for the longest time, and now twice weekly as we're enjoying two tabletop campaigns. We've survived three moves and the gradual loss of members to moves, girlfriends, job schedules, and universities, but we're still going strong; we even have one guy join us via webcam.
Of the core group, I'm the eldest by a couple years, at 32. Also the only female, though our extended group boasts 2 girls to some 8 or 9 guys. At least two members have a Bachelor's degree or better, and I hold two Associates' degrees.
We play tabletops, board games, and card games, as unusual as we can get them (latest fun: Mag Blast; long-term fun: Carcassonne). And then we enjoy Left 4 Dead 2 and plenty of other video games both modern and retro. At least two of us are trying to design games ourselves.
On my own time, I still go back to stuff like Final Fantasy IV and VI, Dragon Warrior III and IV, Phantasy Star IV, Katamari Damacy, Harvest Moon: Back to Nature, Soul Blazer, Brigandine. And I'm raising my 7-year-old nephew on games from Super Mario Bros., MegaMan, Metroid and X-Men to Sonic the Hedgehog and now Minecraft. (My best friend's nephew is similarly being raised on Left 4 Dead and Minecraft.)
So there you go: a whole group of people well over 23 having weekly fun with a plethora of games both video and not, and that love of games being passed on to the next generation.
