Yeah you can beat the game without a walkthrough in fact almost possible I think to beat the game making worst possible choice every time( Won't be pretty) only thing not 100% sure on passing is the final Cohesion check that causes a bad end in the final battle otherwise the rest can be done.
said bad run is also no longer possible in the sense of you can no longer get negative army size and in the future Alina will not be as optional so will also make runs after that change is made better than the current worse choice all the time run
If you want everything you can get or best results in everything you have three main options right now.
1, Thosha Walkthrough
2. Grim walkthrough
3. Download the Calculator and use a word document and spend hours planning a route out that gets you through.
because those are the two most complete walkthroughs that get best results in everything you can with some changes because choice made early on have major effects later
