World of Warships!
It is really very fun, only got into open beta on friday. Compared to other "world of .." games, the gameplay itself is very different but everything else is significantly improved. The interface, the way missions, crew skills, equipment etc work - as a WoT veteran I can appreciate how much they learned about it and how well it's all made.
Also, the game looks great and believe me, there are few things as satisfying in gaming as sinking a battleship with a well aimed broadside
WoWs. Get it and try it - it's free.
And here's a short in engine trailer, somewhat misleading because the game is by far not as silly as it might suggest- but it's exactly as pretty.
