I think the Minecraft game is appropriate for kids. I don't think they will get scared from some stuff. If you will buy it, just make sure that kid is not scared and maybe join him while he is playing to ensure that everything is ok. Also, you can find a good server for little kids in Minecraft here https://minecraft.buzz/. My nephew is eight years old, and he really enjoys playing Minecraft games. So if you think that this will be a good gift for your kid, go on. No one knows your kid better than you.
