Minecraft

Minecraft is a building game inspired by the game open Infiniminer, and created by Markus Persson, the founder of Mojang AB Company. The game involves the player in creating and destroying various types of blocks in a three dimensional environment using a character you can create fantastic structures and artistic creations, along the various multiplayer servers in its multiple modes game.
Minecraft is available to the public for € 19.95 and can be played in single or multiplayer mode. Once purchased, you can play through the website or by installing the downloadable version. Also you can play the Classic version for free.
I recommend this game because you practice your imagination creating worlds and because not all games have to have good graphics to be entertained.
