I finished the game today, it is very good, very fast play. I found the first half better than the second. The two final chapters, 18 and 19 are somehow a letdown, including tedious parts, compared with all the game. However all in all IMO it deserves an A.
It is very important to master the crafting of weapons, I got my main one excellent but I never managed to build or even know what I would like as the supporting weapon. Something I missed is the option of "buying" additional inventory storage since I am a pack rat. At the beginning I didn't use my scavenger robots at maximum that was a mistake.
Graphics are excellent and if you are a fan of fast paced horror games you cannot go wrong with it.
It seems to prepare the ground for a DS 4, I hope so.
If real is what you can feel, smell, taste and see, then 'real' is simply electrical signals interpreted by your brain
