4-10 am? That's crappy timing. Most are asleep or at work during that time.
But it's also what really qualifies as 'morning.' After 1000, pretty much everyone is awake (unless they have 3rd shift or something), so that's 'Day.' 'Evening' begins once it starts getting dark - most places, it's around 1800, so that's true. The only problem is when to end 'Evening' and begin 'Morning,' and if someone has a day-job that isn't 9-5, they generally start work at 0500 ... meaning they have to get up at 0400, making that the beginning of 'Morning.'
At the end of Painkiller, it says some demons were harmed in the making of the game. During Battle Out of Hell, lots of demons were pwnz0red and 0wn3d.
What qualifies is what I say qualifies cause. Fortunately, I didn't have work today because this dude was killed 40 odd years ago so I was able to play it in the morning and do the morning thing. But it was crap.
