I didn't make more because the game is gorgeous and you should experience it for yourself. Putting too much would be like spoiling. Also it's a first-person shooter so it's hard to stop and take a snap. With adrenaline rushing more time is spent on looking out for enemies. I played on hard and it really was brutal. Didn't finish though because one boss battle proved above my skills.
I play on hard to make the situation fair. If the character is shot several times then it should be "rewarded" by death. Also I think it will encourage game-designers to consider stealth or smarter "take cover" programming.
