Just get him Lego = real life Minecraft.
sadly this isn't considered a viable alternative
Minecraft is better on an ordinary PC, the console versions are a bit cut down. Maybe get him a PC? You don't need a very powerful PC to play Minecraft + if you don't like shooters or racing games, a PC might be better for other types of games too.
Much harder and no tutorial.
He already has access to a PC but at 8(and 3/4) he's probably not ready for the "much harder" option
