1. World of Warcraft (WOW) – Blizzard Entertainment has produced many strategic games with the name of Warcraft. The first release of Warcraft was during 1994 where humans and orcs were in constant battle with each other. Blizzard made two more sequels to the game and within those sequels it had many instances wherein players were just allowed to use one character.

Due to the success of the series, Blizzard Entertainment developed an online game where in players from different countries would be able to interact with one another. This led to the finished product, World of Warcraft, which was release in November of 2004. The game allows you to choose through various characters with various talents which will help you through the land of Azeroth, the world of Warcraft.
