One more vote for Grapejuice. There's even a Flatpak now, so it couldn't be easier to install. This is what allowed me to move my whole house to Linux. My kids wouldn't tolerate giving up the game the play more than any other, but Grapejuice makes Roblox seem Linux native. Only issue I've had (and this may only be with Flatpak, not sure), is that bouncing quickly from one game to another several times can leave Roblox instances running in the background, eventually eating up too many resources and causing havoc. I got around this by creating a little executable script with `flatpak kill net.brinkervii.grapejuice` in it that the kids double click before starting a new game.
