Ideally, it would not be a roblox game. I personally would rather not make a roblox account at all. And I want to be able to save progress. I don’t usually end up with unlimited time to play games with him and such. But the game is mostly simple. It co-op, and he likes it.
Played a few of the lego games with my kids, like avengers and Harry potter. They have heaps of save points and were easy enough for my 5yr old to get through but still fun for me as well.
