I'm 45 and have pretty significant problem staying in games - I mean I get bored with games after few hours - either I'm burned out, or games are crap.
I've been playing recently The Last of Us part 1 on PC - barely came out of the city and feeling bored.
Most of the games, adventure ones, have this initial story telling part with small kinda "tutorial" part to help player feel the controls etc - but those introduction parts are pretty long and boring, so when I play new game I get bored quickly just finishing those initial parts. You know what I mean?
