It ties into dudebros though. The only way a game is going to sell five million copies is if they go after dudebros hence DS2 & 3 being increasingly action orientated (also applies to Resident Evil 5 & 6 and O:RC). DS3, RE6 and Colonial Marines should be the point where companies go "well clearly this action stuff isn't working. Maybe we should work on trying to please horror fans, budget the games accordingly and forget about trying to make a horror game that's for people who think Muslim = terrorist." What'll actually happen is companies will go "well this action horror stuff is selling but not selling enough so we need to make it even more actiony! Call Gearbox and see if they'll make an Aliens game where you only fight Weland Yutani mercs."
Large swathes of the games industry has to realise that it's not just dudebros that are in possession of money, that it's not just dudebros who play games and that not everyone wants to play Hollywood style "war is a turn on where nothing bad happens to the good guys!" games. Look at Lionsgate in films; their big budget film is The Hunger Games but they also make films like Saw, Fahrenheit 9/11 and Hotel Rwanda, smaller budgeted films that won't bring in THG profits but they'll still make money because they've been budgeted accordingly. A lot of games companies however have this model of throwing a ton of money at a game that doesn't need it then needing it to be a COD killer in order for it to be profitable and that means diluting the formula to be as all inclusive as possible.
Large swathes of the industry has to change or next gen is going to be a slaughter.
