Nothing ever really dies when it is defeated as it regenerates for others to play when they enounter a thing. It is a massively multi-player online role playing game that allows you to play one of several race choices and either Alliance which is generally accepted as good, and Horde which is generally accepted as bad; its all relative, and you can choose a class from priest, druid, paladin, hunter, warrior or rouge among others. The game itself is an immersive world where you can interact with others playing the game from around the world and being social is something pushed by the makers of the game.
Unfortunately, yes. The game, originally, was a PC game and it was very fun to play. They stopped the standalone in preference to their online pantheon of games. They even made a movie that wars released to theaters and now available on many streaming services.
Thanks @Ivan Tea Sanderzon i don’t play those type of games, but thank you for joining in the games section
