That was ten years ago, and I still don't know if I struck the right balance. Parenting is hard. If you have young kids today it's a good idea to understand what games are popular and what their business models are.
It depends strongly on kind of game, and especially on the business model involved. Gacha games, free-to-play, and similar models are very much optimised around addictiveness. Personally I've found that story-based finite games, i.e. the ones you play through and then you've experienced it, are much better in those respects. Unfortunately those seem to become much more rare these days.
This has not been my experience at all. It's very easy for me to play a few rounds of rocket league and keep my daily game time to under an hour. When I play stuff like Zelda BOTW though, I have to use the parental controls on myself or else I'll spend half of my day on it.
The PlayStation doesn’t seem to do that, although my son gets in trouble more often when it’s time to end because there is a higher level of effort to get out. But it doesn’t seem to zombify him.
However I think it speaks that everyone has a different approach and solution to how they play games. It then becomes interesting to see what they play and how they limit their self.
IMO it was addictive, but only to certain personality types. Mine is definitely one of them. Others would see a difficulty spike and/or the amount of re-treading they need to do to make progress as a deterrent.
Recent games are more addictive in a way that appeals more widely.
In reality for certain personalities (myself included) that focus on mastery is actually the addictive bit, and I think its a productive addiction all things considered. Im not addicted to the mind-numbing aspect of playing, I'm addicted to the huge amount of knowledge I need to gain in order to succeed. Its the same reason I was drawn to DOTA and Magic later in life.
Of course, the incentives were also a little different. Old arcade, for example, games wanted you to drop in more quarters. So they had to find ways to make you lose. But not just lose, lose when you're just close enough to the next level.
One more level
Just after this boss
I think single player games now are just as addictive as they were then. Especially when you look at indie games (Shovel Knight, Death's Door etc).
The moment interaction with other players happens is when I feel a higher bump in addiction can happen. Loot boxes, seeing a cool skin etc.
If I had a kid they'd have a laptop running Linux with all the open source games (and some of the older Nintendo ones on emulators) and probably a collection of older films on DVD.
