You can unlock all scenes in the gallery automatically, this way you have most of the content.
Save files have little worth, since you can't revisit scenes. A complete save file would bring you at week ~70 with high stats, full research and upgrades, but nothing to do. If you want to see the content, play the game yourself (or watch the scenes in the gallery).
Since the game is still at part 1, there isn't much to guide through. Visit the village above your starting position, conquer Fort Raeve by sending a spy (research brothel and buy the tavern first for money) or military numbers (research Orc quarters asap). Orc camp has 4 outcomes requiring some skills and assets. Main City has three outcomes, Goblin city only has one outcome as of now.
This guide is good enough for Raeve and Rastedel.
