I tested Requiem yesterday and I'm amazed! It's a whole another feeling of playing the game.
In Helgen Keep I kept fighting with Ralof to get through, shooting some arrows and dealing some damage, but not very much. I even got hit by an arrow, but somehow I lost only 1/3 of my HP. The spiders made me sh** bricks with their poison! Right after I got out of Helgen, I had to be really careful. Before me was a wolfpack with about 6 wolves! I had to sneak around them. Then, I walked into a bandit camp, which was warning me not to step anymore closer. So I turned around them and found a way to Riverwood. The world is much more dangerous and realistic now, thus you feel much more immersed. Imagine: You get out of Helgen as a weak prisoner. They had your hands cuffed. You grabbed some armor and a sword, but can't really handle it since you're not used to it. How should you be able to kill a wolfpack or a bandit camp right in the beginning, like you did in Vanilla easily? Makes much more sense I think. It gives the game a Gothic feeling (that's a cool old german RPG), where you're really weak in the beginning and even fear a lone wolf to attack. And with time, you train and become stronger and stronger.
However, when someone is turned off by being oneshot from Arrows in Requiem, you're free to adjust the arrow damage in the menu I think.
This is the time where I'll play through the game, I think, I just need to tweak the performance now. My highest lvl was 15 before.
