Pretty much no one looks good here. Marty definitely comes out looking the best for sure though.
I don't see it that way but maybe I'm misinformed? All activision did was not like his work and changed the music and Marty freaked and tried to rile up the Internet. He also threatened staff and tried to subvert the release of a trailer which is advertisement which is what Activision is supposed to be responsible for.
Then when he returns from vacation he is still pissed and doesn't work hard and gets fired essentially. Bungies beef with Marty was that Marty was elevating his music over the entire success of the game and his actions pretty much Show that to me.
He deserves his stock and I'm glad he got it but if the court documents are true Marty was rightfully terminated. Seems like the court got it right.
