Plenty of great tools for kids to start making games with if they're interested in it! Personally, I think running something on a Raspberry Pi isn't very interesting or inviting as a first thing to play with. Creating a game in Roblox, designing an outfit in Roblox, or building a game within Minecraft is more interesting. And people build crazy stuff in Scratch.
But also, not every kid is interested in that anyway.
They used Scratch at school, but you might be right about the Pi just not being inviting.
