- Sneak the time when you can
- Play games with them
- Wait until they are 12 (-ish) and they decide you are uncool
Otherwise, you're doing what I ended up doing. There was a long span that, I just... never played games because I was too busy. I regret that a bit because it's a thing that makes me happy and even if I'm "Dad", I'm still a person that deserves some time for "me".
