38 here. My clan has one 45 year old, two 38s, one 37 one 35 two 33s a couple 30s and a few people in their late 20s. Hit me up if you're looking for some folks to run with.
About to turn 31 next month. You're not old. My bro is 36, married, father of 3, great job... I feel happy for him.
And he still plays a shit ton of video games. I feel people within the 30-40 age group are the real gamer demographic.
