I guarantee that it is impossible to skip this game completely, there are more side quests than the whole story of the game. I've crossed it several times, but mostly in the winter when I don't go out anywhere and that's when I have the most time because it requires a lot of free time. In order to press it, I would need an average of 3-4 weeks of playing for a couple of hours every day. Every recommendation, the graphics in place of the story as well as the entire Wolfenstein series are phenomenal
