Alright, I noticed all your questions about the walkthrough too late sadly.Whatever, it doesn't matter anymore. There is a better way to structure the walkthrough. In the end, that is all I am trying to say. You guys have turned me off to this game. The structure of the walkthrough is all over the place. If you tell me it is perfect, I will tell you that you are lying. But, with helpful community members like you Samovych Hydzinski, why would I even want to play this game anymore? Delete and cancel.
The perfect walkthrough doesn't exist. Some will prefer it to guide them without having to use their brain, others will prefer loose guidelines. What works for you won't work for others, and vice versa.
Now for the meat of what I meant to tell you: this is not a game you are meant to play once and be done with. This is a game that encourages replayability. Just to give one example: at one point, you must choose whether or not to help King Eric's brother. That's quite a decision, right? One that will lock away quite a bit of content regardless of what you choose. You can later replay the game and choose differently, for this particular decision and many others.
That's why it's better not to follow the walkthrough at first (unless you're really stuck). Play the way you want, see the outcomes, keep going... and once you're satisfied with your first attempt, you can start another playthrough with newfound knowledge. That's when you can start checking the walkthrough for events you might have missed, when and how a route branches, etc. You'll never complete the game 100% on your first playthrough, so it's best that you don't rely on a WT to do the impossible anyway. It'll only leave you frustrated and might be why you were confused as to why the WT was organised this way.
Hope you can enjoy the game now!
