Mine started with racing games F1 Race Stars (basically Mario Kart for the PC), Flatout series particularly Flatout Ultimate Carnage, Wreckfest they loved. They have played all the Lego Star Wars games. Then as the years have gone on Fortnite, Mincraft (Windows 10 version) Roblox, Star Wars Battlefront I+II and now Star Wars Squadrons. Apart from Roblox I play the other ones with them and my eldest (nearly 11) has started playing a Medieval Multiplayer game cant remember the name of it but it has massive battles in it. He was interested in it after doing Medieval times at school. They even have their own Discord channel where the school mates, and other friends hang out and chat about all sorts.
With regards to content control you cant beat Microsoft Family. Controls content, when they can play, how long they can play, if they are naughty I can reduce their hours. Plus if I want them off the computer (meal times or just plain annoying/being naughty) I use the app on my phone and instantly logs them off the computer. Best thing MS ever invented. Before Covid my wife would txt me at work and say eldest is misbehaving can you kick him off the computer, out comes phone, quick press on the app and bang no more computer time. (both have their own gaming computers, gaming chairs, RGB the lot)
