Its a common misconception that you cant game on Linux. Whilst gaming on Linux has been made possible by Steam for example Team Fortress 2, Lutris have bash scipts that make games work on Linux. With more games being added constantly why not see what Lutris have today.
The only real draw back to Linux is your graphics card driver MUST be up to date.
Here is a list of just some of the games you can play:
- League of Legends
- GTA V
and many many more
