This site is great, but I am still unsure as to why my child needs an account. He currently plays on both xbox and iPad but tells me I need to buy him a $30 account for him to access better gameplay. But I can't find a straight answer as to what the money gets him over what he already has. I hope you can help answer this? Thanks.
The $30 version of Minecraft is the computer version. It has a few more things than the Xbox and iPad versions, but the main difference is that players can apply mods and resource packs to change the game and add new stuff, which is probably why your son wants it.
If he wants to keep playing the iPad or Xbox version then he doesn't need to pay any extra for anything.
