World of Tanks makes sense. It’s Counter-Strike with moveable turrets; angry houses hiding behind placid houses, streets like corridors, cannons like machineguns, machineguns also like machineguns.
World of Warplanes makes sense, sort of, on paper. Planes. They’re like tanks but they fly. Except there’s no cover in the sky, and enemies could be in front, behind, beside or above you. So you sort of just wheel around in circles forever and it’s alright.
World of Warships? That doesn’t make sense at all. How the hell would you make a multiplayer game out of something like that?
