Not gonna link to any of the channels, but walkthrough/LP vids are already popping up on youtube for the game, I haven't watched any outside of seeing that it was clearly new footage, so that is one option if you are desperate to see how the game is handling its humor later in game. They will probably be pulled down or they may just let it slide since it is so close to release, either way its an option to see more of the game at the time of this post.
There are twitch channels since a few days and they do not get pulled down at all. Someone actually finished the game 3 times already on twitch. Games length seems to be 15 hours with doing some sidequests so thats perfectly fine for me.
As for the score I am not really worried from what I saw it is great. However I really can not wait for some social commentary how you can not chose a woman as character or how this scene is racist, sexist etc. I really hope someone will something stupid like that with this game XD
Wait, can you not play as a female in the game?
