1. it can be dark quite often, some places have light switches. You have flashlight and nightvision gadget.
2. it is imsim, it is up to u. 10-20h my guess on avg.
3. there are pin up style magazines you can find, but not many.
4. i had so much ammo on the hardest difficulty I had to throw it away. Even if you are not good at finding stuff, there are a lot of ways to deal with enemies.

I very much appreciate that you took the time to answer my questions. I am considering making a purchase as the demo was quite enjoyable for me and it was interesting how much I could do and things to do.

The only thing I did NOT enjoy was that every time I died, I had to begin at the very beginning and I was lost quite often.
