I am a total fan of World of Tanks, an online WWII MMO where everyone is a tank! The objective of each game is to either wipe out the opposing team, or capture their flag. Simple and awesome concept. My favorite vehicle by far in WWII is the hetzer, which I get to command ( much to the chagrin of many of my mates) in battle.
One of my better days. A Hetzer's gotta Hetz!
Not my best moment- stuck on the bridge... I actually survived the battle!
The game is free to play, goes from beta to live soon, and I encourage you all to check it out! If you do, watch out for my mighty hetzer! http://www.worldoftanks.com/
