Hum did not know that, I guess I would need to know what state it was in back then. But then again, I'm pretty sure Marathon was started under Sony tutelage, so I have my doubt that Sony would have stepped in and stopped them.What's interesting is that the dev behind Concord was only acquired by Sony halfway through development. Initial development took place under a company called ProbablyMonsters. Not sure why Sony decided to buy the dev, maybe they believed in Concord, but the lack of advertising kinda points to that not being the case and them wanting something else.
