The state of California has intervened in a lawsuit against League of Legends maker Riot Games by former employees alleging gender discrimination and sexual harassment.

That's according to The LA Times, which report that the state government feels that the preliminary settlement that the two parties reached - $10m to the former employees - was nowhere near enough. The state of California reckons that $400m is a more appropriate figure.

“We are particularly dismayed that the filing downplays and ignores the efforts we have made with respect to diversity, inclusion, and culture over the past 18 months,” Riot said in a statement to US political outlet The Hill.

“The Settlement Agreement includes a long list of the dozens of meaningful initiatives and changes we have made, including updates to our policies, in response to [games website] Kotaku’s reporting and the class action lawsuit. We believe that these initiatives demonstrate a real commitment to actual change that goes well above and beyond what most companies would have done in a similar situation.”

This follows a damning exposé from Kotaku into Riot's working culture, with the League of Legends maker saying that it is working hard to change its internal problems.
