I had recently purchased Minecraft from the XBLA store. After playing it for at least 4 hours, I can safely say it is amazing. This has to be the best purchase I have ever made on the Games Marketplace. Please see below for more in-depth details.

Gameplay:9.5/10
Staying true to the PC version of Minecraft, the Xbox port has a similar control scheme. Crafting has been put into a very nice (yet a little confusing) panel and the mobs still work as they did in 1.5
Altogether it stays true to form

Sound:10/10
The music in this game did not change. It is the same as the PC Port

Multiplayer:10/10
Multiplayer is invite only, but still extremely fun. It supports up to 8 players and gives each a personal skin (although they are not good skins)

Overall I say this amazing port of an amazing PC game gets a total of 9.9/10
