Tried out the demo for Fire Emblem Warriors: Three Hopes. They really have learned since the first Fire Emblem Warriors and Fire Emblem: Three Houses. Every class has its own playstyle, every student has their own unique ability, the protagonist is voiced and has actual personality, and the students are locked to their routes with some special units unlocking only in their route. Not to mention this game is appearing to do the butterfly effect properly, and the start of the game thus far, even to the Time Skip, does not change depending on route. You do the one for Golden Deer, it tells you in summary form what happened in the other two routes at the same time. Same if you do Black Eagles or Blue Lions. Sadly the demo is locked after the Time Skip (only allowing you to do the extra missions there but not the chapter quest), but I have to admit I'm impressed, they fixed all my complaints with the first FEW and managed to even throw enough curve balls and Author Saving Throws to make me love where the story is going. Some spoilers below because I have to gush.

I mean, you save Monica from Kronya, who then JOINS YOU IN BLACK EAGLES. You get to see Holst in Golden Deer run. The Slithers are exposed early so the story starts flowing quicker and easier. A shame this entire thing is a What If? scenario, since Shez was originally supposed to die in the first battle as that's what led to the normal Three Houses timeline.
