World of tanks is a MMO (Massively Multiplayer Online) game in which you buy and upgrate tanks from tier 1 (the lowest "level") up to tier 10 (the highest "level") that were used in the second world war.You can choose tanks from differend countries:

                          -Gemany
                          -France
                          -USSR (Union of Soviet Socialist Republics)
                          -China
In world of tanks you start a cca. 15min long battle. You are in a team of 15 players who fight with you against an oder 15 player team.
There are 3 differend battle types:
                          - standard battle: every time starts the battle at their own base, the battle is over untill your or the enemy team captures the opposite base or destroies all the players of the opposite team
                          -encounter battle: there is only one base for which you and the opposite team battle to capcure
                          -assault: only one team has a base and the other team battles to capcure it
When u start a battle one map out of a series of maps is chosen.

 
I like the game because you don't play against the computer but against players all over the world. I also like the time period.
You should check it out sometime.
