4. Counterstrike

Banana's are OP.

With prizes as high as $200,000, Counterstrike takes the spot for the most profitable Esports Game in the FPS genre.

It also takes the prize for the game with the most hacking Russians, but when you take some; you’ve got to give a little. Counterstrike has evolved over the years since it's original release in 2000 and has seen several improvements.

The game was first a port over from the Half-Life 2 engine into a first person shooter. The game received massive attention and has remained the FPS king for over a decade, and it’s not going away any time soon.
