Somebody has explaining to do...

I'm going to high jack the comments to ask this because I didn't know there was a minecraft sub and this is sort of off topic to the post but I'm going to ask anyway. So my son just turned 4 and when he was 3, my friends' son who is 6, showed my son minecraft one day on his moms phone and my 3 year old was hooked and I didn't know anything about it (I'm not an old, naive mom or anything!) Well he was watching kid stuff on YouTube and one day he starts randomly watching minecraft videos on YouTube and I let him until I heart some of them cursing. He was upset I took it away so I searched, "minecraft videos with no cuss words" and now he watches a guy named "Stampy" and watches him obsessively. So I decided to buy the pocket edition of minecraft on his tablet and got on and was like it's just a guy, grass, trees and stuff to build with and nothing else. So I played around on it and there wasn't much to it at all, so I gave it to him and let him do his thing and (mind you, he just turned 4) eventually he shows me his minecraft game and he has a ton of worlds and amazingly nice, huge houses properly built and he's got all these other minecraft people walking around and he's got enormous spiders that he tells me he spawned and he explains to me that the creepy ones are creepers and he has pet dogs and he has railroad tracks and trains that he rides in and built pools and houses up in the sky and has other villagers walking around or whatever. He's crazy good and I was just wondering, is that normal for a 3-4 year old to be that good without any help besides watching videos from Stampy? Now he's watching some purple haired girl on YouTube and I allow it because she doesn't cuss but is that ok too? Is there something else that I can get for him that is better than this minecraft app that I bought on his tablet?
