World of Tanks

[Seraph]

I'm surprised that no one has yet to mentioned this game yet.

As the name implies, the game is a PVP using various real world tanks(if only on paper) from the 1930's to early 1950's.
I should the note the game does lean towards the simulation side with many of the tanks' stats are based on real world values and there is some grinding so I suggest you try to pick what tech tree you go down carefully.

Now the teasers are also quite amusing as they parody some other gaming genre.
