As big a Trails fan as I am, I still haven't finished Reverie, and it's been so long, I'm planning on restarting the whole game after I finish up with a few other games I'm in the middle of. So I don't even know all that much about the Daybreak arc right now. Try to go into these types of games pretty blind.
Whenever I get to this one, I'll still probably buy it for full price. One of the only series that I'm willing to do so. Definitely not the "complete edition" because damn near all DLC for Falcom games are costumes and extra in-game items like consumables and crafting materials. Never worth it.
Am also curious about how the game is contested so much. It's certainly not a first for the Trails series as the Cold Steel games were pretty contested at times, especially CS4. Even though I still overall enjoyed CS4, there were definitely a lot of decisions that I was not a fan of, some that ended up retroactively affecting events from the previous games.
Still, no matter what, I still enjoy much of the overarching stories that happen within the series, so it would have to be a pretty big fuck-up for me to drop it.
