I'm looking for games that I can play and enjoy with my 8 years old son. It doesn't need to be a 2-players game, or even a game that he can play (though if he can take the controller and get actively involved, that's better), but just something that he can enjoy as a "backseat player". We have a Switch, a PC, and a PS4.

tl;dr: "backseatable" adventure-ish games with exploration and a clear direction (different sights to see, and a sense of progression), puzzles (so he feels involved when exchanging ideas), ok with light horror. Low stakes, low stress.

Here are some games that we played together and both liked:

• Outer Wilds: loved it so much we did 2 playthroughs in 2 years. He liked the sights, the exploration/treasure hunt aspect, the puzzles, and he asked me questions about our universe and solar system. He was mostly passive as a player both times we played, but we were sharing ideas and he was making suggestions on what to do/where to go next.
• Link's Awakening remake: we played this one when he was 6 years old, with me taking the lead for the bosses or more complicated puzzles. We finished it together.
• Stanley Parable: I intended to play it alone, but unexpectedly he really liked watching me play.
• Strange Horticulture, Grim Fandango, Day of the Tentacle: he liked solving the puzzles with me, and me explaining/narrating what was happening and why.
• Portal 1 & 2: he was able to play on his own with some help, and the coop levels in Portal 2 were great.
• Deep Rock Galactic: he's making his own story and narrating along while I (and sometimes random players) play normally.
• Human Fall Flat: he loves the slapstick humor and finds better (and more creative) solutions than I do
• Mario Odyssey: probably his GOAT game, the accessibility features helped him a lot to play and enjoy it alone.

He's also taking an interest in light horror (specifically mascot horror) games:

• Garten of Banban series: objectively bad games but he really enjoyed the progression, light puzzles, and the liminal level design.
• Indigo Park: much better production value, mostly a walking sim, but very short.
• The Complex: a free "Backrooms" game. He didn't play it since he wasn't yet comfortable with mouse and keyboard controls, but liked watching me explore around
• Crow Country (demo): he backseated and enjoyed it. There's an "exploration mode" that removes enemies. Will probably buy the full game later.

And some "failed" tentatives:

• Tunic: since he liked Link's Awakening, I thought he might like Tunic, but no. Probably because of a lack of NPCs or clear indications, and the game is too difficult for him. Not fun to backseat.
• Zelda BOTW: he tried to play it when he was a bit too young, and had a hard time with it. I'll probably try again soon.
• Minecraft Dungeons: we played 2-3 games but he got bored of it very quickly.
• Diablo 3: he saw me playing and wanted to try it. He liked it much more than Minecraft Dungeons but hated seeing villagers getting turned into zombies, so we stopped here.
• Sandboxes: not his thing (Minecraft, Terraria, No Man's Sky, Animal Crossing)

So in summary, I highlighted the best experiences we had (with Outer Wilds being the best), and I'm looking for something equivalent.

EDIT - I'll try to keep this post up-to-date with the suggestions we liked:

• Superliminal: Excellent, I wasn't expecting such a good game. He's managing most of it alone, and there's even a (harmless) "scary" section
• Untitled Goose Game: Great suggestion. We actually already played it (not to completion), and he loves honking and absolutely not helping me complete the objectives 😅
• Layton series: I think he tried the first one on my DS for an hour or two. I'll suggest it again and be the backseat player myself.
• Luigi's Mansion 3: GOTY

Has anybody had much experience playing DnD or other tabletops with children? I've been toying with the idea of making a fairly straightforward and simplified RPG using Story Cubes and GURPS that kids can get involved with easily and have fun playing. I'm specifically aiming to play with my daughter (8) and my niece (5) on a big family holiday in August, though I see no real reason that this couldn't work with adults as well.
Essentially, the conceit would go along the lines of each player rolling a limited number of story dice to help with character creation and such. I'd ask the players a few simple questions about their powers (for example, are you more of a wizard or more of a warrior?) to get some basic stats stats together (STR, DEX, INT, CON), and then use story dice myself to quickly improvise a short one-shot session.

Does anyone have experience playing with kids, and if so - any pointers? Am I being too ambitious about children's ability to imagine stuff in this way? If so, are there any good systems out there that are good for young people to pick up and get stuck into roleplaying with?
