From a narrative stand point, I think it's great. Gameplay wise, it's iffy. So many units are punished so badly from a lack of availability, especially the majority of part 1 units, more so units who are new to RD which really sucks cause the new units are already hurt by a lack of any character depth due to the shitty support system so them being hard to use hurts even more. However, despite this, I still do think its cool and really made RD's story feel like a grand spectacle and an actual war and did grey morality and dramatic irony pretty well. Like Florete said, I'm happy RD did it but I'm also happy for it to remain a RD only thing.
