Exactly, like when they streamed a while ago and gave the clue how to get inside the church and spoiled all the fun part of how to plan your things on your own. I think it is still good they show players what to expect from game, but they really should not go so deep in, not that they do with other videos I saw.
Especially when closing time is so soon and after it gets released, people will just run through, because they will know exactly what to do from these streams. Not that they would not know from later play through, but it does not need to be part of the show for fans who are neat for details that will easily spoil themselves. Not that I care much about spoiling myself a little, but you are right about this one.
I asked Tobi on this stream about demo. I know that they do not want any other early access, what I actually meant was if after they have game finished or released, if they put out a demo too, but clearly it is not their plan. As they had to create intro for PS4 before installing full game, I thought they might make this "demo" for PC as well.
Just side note for Tobi, "Are there any extinct animals living in game?" Someone mentioned some nowadays extinct animals which were living in that region in past could appear in the game. Not that I meant fantasy stuff, but there were animals hunted by locals which disappeared.
