I think at this age kids just naturally want to have their footprint in the digital world. Games is just an obvious space.

On the same subject, when my 5yo came up with a very detailed comic story, all hand drawn in a span of two days, we just scanned the drawings and put them in a video sequence.

Sure, the grand vision was some real action, but seeing his work digitized and animated has served it's inspiratory purpose.

Also, it gave this 5yo some ammo in conversations with his peers who would brag about "creating their own game in Roblox".
