I worked there for a very short time as a consultant and I remember Barry. I remember being astonished at some of the things I saw and heard at that company and I am surprised it's not them getting the scrutiny and instead the larger tech companies.
Working at Riot Games was like working in a frat house where you get paid, and I mean many of the bad parts of living in a frat house. Of the places I've worked, Riot had to have the lowest median age (early 20s), which probably contributes to the problem. The guys could be assholes, but I fear that some of the women, being young and this being their first job and an amazing opportunity, get disillusioned into thinking that this behavior is normal in industry and that is really sad.
I am surprised not more have spoken out. Riot (and other gaming companies, not just Riot) has some of the bro-est culture out there and it's going to cost them in a lawsuit, just give it time.
