If they were then SC2 did great for the company.

1M copies were sold in the first 24hours and around 3M in the first month itself.

The expansion Heart of the Swarm sold 1.1M in the first 2days of launch.

Dota2 on the other hand is free-to-play, of course there are items to purchase in game but since it isn't required to buy to play most play the game without buying anything.
