Hello. Today I will be doing a comparison of xbox and pc versions. Let's get to it! The Xbox is good if you want to build something really big, or invite friends to play on splitscreen. The pc version is best if you want to build with redstone, on have mods, maps, and servers. The xbox version is less developed, because you can't have commands (which means no command blocks), there is less blocks, and there is no pick block. The default key on pc version for pick block is button 3, or the mousewheel. Pick block allows you to grab the block you are looking at without going into the inventory. It only works in creative. Then again, the Xbox version pre-owned at Gamestop is $10, compared to the PC's $29.99, so its definitely cheaper. I think that they are pretty equal, because of the Xbox's multiplayer. It depends on what you want.

Xbox $19.99: new at Gamestop
Pocket Edition: $6.99
PC version: $29.99
