Combine that with good story and interesting characters, and for me personally a great setting (wich Dutchman wouldnt like to kick the germans out of his own Holland?) and interesting scenario's being brought to life (for example the bombing of Eindhoven after the allies liberated it, of wich there are screenshots and by just looking at those i allready feel the shivers down my spine

)
And they capture the feeling of our country very well IMO, it looks so Dutch.
Yeah, exactly. For me, one of the most important factors of this game will be the scenery and atmosphere of the Netherlands in the 1940's, and it looks like they did that pretty well. I'll probably get the game for that reason alone.
The cover system looks pretty cool... the way you look over his shoulder, it looks pretty real. The iron sights look neat, too.
People here always complained about not being able to sniper0rz their way through the level and shoot every German toe that's sticking out of cover, but I call this a good thing. At least BiA had pretty realistic firefights, and it focused on fire and manouvre tactics. Realistic feeling firefights = good. So BiA HH might not be the most realistic WWII shooter ever, but it will FEEL realistic. And like SiC said, it pays attention to characters and story, which also increases realism.
The AI of your teammates though... terrible, and it really brought down the game for me. I hope they make that a heck of allot better, but I doubt it... great teammate AI hasn't been done in a game yet. Also, I don't like that grenade explode effect, it looks like something out of Star Trek.
It seems the person who made that video played on Easy difficulty. The game better be more challenging on the higher difficulties.
