Launched in December of 2018, the store is said to generate $680 million so far from 108 million PC customers.
Yes, Epic's own Fortnite is the money maker here, but the team states that $251 million has been spent on third-party PC games.
One of the biggest advantages for customers has been the distribution of free games, of course. The team has given away 73 free games to players that have been downloaded more than 200 million times. They have also announced they'll continue offering weekly free games throughout 2020.
Another important point is the exclusivity of some of the games released throughout 2019. Here are some of the exclusive titles: Dauntless, Untitled Goose Game, Outer Worlds, Borderlands 3, Metro Exodus, The Division 2, Control and more.
