As a combat veteran of the US Marine Corps, these modern BF/MoH/CoD games are about as realistic and serious as Halo.Are the "WHAT" and similar replies on the first page sarcastic? What he said makes a lot of sense. The masses are turned off by non-realistic tones in these games. I'm saddened by it but it's reality.
I suppose it's just "perceived realism" that's important, not actual authenticity.
People want realism? That was Full Spectrum Warrior, ArmA etc. People don't want that. People want seriousness? That was Spec Ops: The Line, they didn't want that either.
They want power-fantasies.
I reject the notion that you can't make a "realistic/serious military shooter" with a good dose of appropriately placed humor that will be palatable to the wide-audience.
In fact, humor and cynicism is about the only way to keep your sanity in real-life warfare, but whatever. They're making these games for fantasy hungry teenagers that like to watch shit blow up cool, not people that read history books and watch documentaries.
