I have played games with my nephew's before, and my 5 year old daughter plays Disneyland Adventures but I'm at the age now where I don't want to game online with other kids. My gaming time is precious now and don't want to waste it being told by some kid he has Fu***d my mum
Exactly how I feel as well when playing games on my PS 4 with my younger ones. The thing is that you get to see new tricks that they do and you be like wow! They've got something up their sleeves. Playing games with them, as long as they don't keep beating me, is pretty fine.
It can be fun playing with kids. Though not all people have that much patience. Especially if those kids are not much aware of that game. So the process of getting them to like the game and also making them play on par with you can be painful. And in some context some of the games of kids are harder to play from our patience context.
Echoing a bit of what Nova has said, it does require a bit of patience and a 'letting things go' attitude for me anyway when I sit down with some of the younger members of my fiances family for a quick game or two. Obviously it's just because they're a kid so they can't play at the same 'level' that an adult could but by Lord it's hard work sitting there watching them poke away at the controller like a lost person. Take's all my urges not to scream "just press that bloody one" and take over haha.
