It’s best not to buy it, although it’s cheap. If you are really a fan of StarCraft 2, you can go to the official website of StarCraft 2 to buy it.

This way you can rest assured. In fact, I personally think you can if you have enough funds. If you are considering not buying enough, you can download the digital version of StarCraft 2 and then download StarCraft Butler and install it in the directory of StarCraft 2 to play single player and skirmish battles. I like this game so much that I asked a friend to buy it from Australia. This game is really great.
