elementaryos is made for that sort of thing, its quite simple and friendly and you need to poke around it to get it to even be able to do more ‘advanced’ stuff. its among the most polished DEs ive seen design and user-experience wise.
and it is still linux so you can disable or otherwise restrict their user account from anything you don’t want them meddling with. like the settings app and stuff, try it out on a VM and you will get what i mean.
oh its based off of ubuntu lts so its solid
it helps that linux can now run almost everything else now instead of almost nothing. the main thing is we have options now.
thank you based valve & community btw
