According to some sources, the data of which, however, remained unconfirmed, the much-anticipated StarCraft II strategy cost its creators an astronomical amount of about 100 million US dollars. Prior to this, the record belonged to Grand Theft Auto IV.
But the named amount includes only the cost of developing the game itself. That is, you need to add to it the costs of marketing, as well as other related costs. However, sales of the highly anticipated game are expected to bring Blizzard at least a billion dollars.

StarCraft II is one of the most anticipated long-term projects. The first unofficial information about the start of development appeared in 2003. The official ones - in 2007. It should be expected that hundreds of thousands of copies will be sold in the first days of sales for both the PC and Mac platforms. The company promises a trilogy, the first part of which - StarCraft II: Wings of Liberty - will go on sale in the very next few days, namely on July 27th.
The first version of the game appeared at the end of the last century. She was also expected for a long time, the announcement was constantly postponed. But the result exceeded all expectations - more than 11 million copies of the game were sold over these 12 years. And it is still being played all over the world. And I think that they will play even after the appearance of the second part.
