Trouble is, most of the other games out there for kids are the same thing as the roblox games, and many of them cost money upfront, then sell the kids on skins, and tiny game functions just like roblox games. It's hard to find suitable games for kids, and takes a ton of energy.
I have gotten my kids into satisfactory, raft, and games like that. But my youngest keeps coming back to the grinders which all have pay to win. Good games are just not as profitable.
