Played some more hours. New status report: Difficult level is getting a bit higher, though it's not super total high yet. Radios are more or less easy to find. Even if not, I don't die and have to do ****load of save&loads like everyone wrote in their reviews. I am running a bit low on ammo in the moment, but it's still not a big deal.
/Edit: About Christine. I really like her and think she is the best of the three companions. Though, her subtitle-like dialogue is kind of annoying to me, because of two reasons:
1. The text is too fast. I have to jump over the lines, before the next line pops up, which is really annoying. Especially because english is obviously not my main language, so I need a little bit longer to fully understand everything.
2. The dialog is telling me what she does, but the visual does not. I know why this is how it is and I know it would have been lots of work to create new animations, etc. so I can understand how it was dealed with. Still, I needed some time to get into this, because it for sure was distracting for me first. I mean... in a Fallout game like the ones we know from history books, this wouldn't have been a problem. But in this "oh, first person perspective is soooo immersive! We can't do any other rpgs anymore, because first person perspective is... sooooo immersive and back in the days the devs just have been limited!"-time it feels wrong to me.
