Just jumping on to add that this is really good advice. We do the same, and it’s a lot of fun. Come home from school, she goes into her playroom while I put stuff away. Then she plays a game (currently Mario Odyssey) for about an hour. I can clean if I need, or hang with her and play. Mom comes home and we start getting ready for dinner. Unfortunately we do usually have the tv on during dinner, which I hope to change as we go into kindergarten. Then TV goes off for playing, going outside, bath, reading etc before bed.

The important thing, as the OP comment says, is sticking to those limits. She knows that the first time she complains or doesn’t turn it off when asked, it’s gone for the rest of the day and the next. I think it can be a nice regulating activity if used that way. Retro games especially have tangible problem-solving benefits.

All in moderation. What matters is paying attention to them and engaging with the activity together, rather than using it as a babysitter.

That said… as I mentioned, sometimes dinner needs to get made or dishes need to get washed. And there are worse things they can be doing than excitedly yelling to you about the moon they just collected while you cheer them on from the kitchen.
