Accessibility of roblox, gotcha life, etc?

Hello all, I never post on here but am facing a bit of a conundrum. I have nieces and nephews that are big into gaming. They want me to play with them. Their current obsessions are gotcha life, among us, mine craft, and especially roblox. Are any of these accessible for yall? I’d love to play with them and its darn near impossible explaining why I can’t.
