im 32 and i still game. not as much as i did in years past, but i have a ps4 and x1 and pretty much get all consoles when they first come out (other than wii-u cause its LOL). but i don't find myself playing the games i used to. at this point i'd almost consider myself a niche gamer in a sense. the only games that i play repeatedly are fighting games.
i will play racers and games like tomb raider or uncharted, but i play them once then never again. i love the single player stories.
but right now, all i play is killer instinct and that is all i've played since xbox1 came out. prior to that it was street fighter 4 for the past few years, with other games scattered in between. i'm pretty much over FPS games though and rarely play them, other than maybe the single player aspect of them.
i do also love arcade racers but it's been a long time since a good one came out that kept me engaged. oh, and hot shots golf 5 on ps3 was my secret little piece of crack that i was addicted to as well. i hope ps4 gets a new one.
i only play like 1-3 times a week though, usually for an hour or 2. it will either just be on a weeknight or weekend when my wife is asleep. now that it's warmer weather my time will probably go down a bit though. but when it's a single player game, i'll usually beat it in 3-4 days playing for 3 hours or so a day, just because i get sucked into them.
