Overwatch League is finally here.

After months of fanfare and anticipation, Activision Blizzard Inc. (ATVI) - Get Report kicked off the first night of its inaugural season of the e-sports league Wednesday, Jan. 10, and the reaction was overwhelmingly positive.

Users on Twitter and Instagram documented their excitement watching the first matchups of the 12 teams vying for the champion title and $3.5 million in prize money and performance bonuses.

But there was one letdown a few social media users were quick to point out: Overwatch League's lack of female players. 

The season will be broken into four stages, with each stage lasting five weeks. During each stage, teams from 12 regions split into two divisions compete in a series of rounds playing the Activision game "Overwatch." Matches will take place in the Burbank, Calif., arena that was built by Activision Blizzard.

With merchandise for sale at the arena and tickets ranging from $20 to $30 (and the inaugural match a sellout), Activision Blizzard looks set to benefit from the Overwatch League already. Investors took a liking to the first day of competition, sending shares higher 2.12% to $68.25 in premarket trading on Thursday, Jan. 11.
