Finally completed this. What an experience. The gameplay did get quite repetitive nearing the end, but the story, world (or canvas..) and characters were definitely the highlights.
Even on story mode (used it to learn attacks), a certain few bosses still would destroy my party within 2-3 strikes. I give Clair Obscur a solid 9/10.
Maelle's ending was surprisingly depressing and gave me the feeling that she wants to be an even bigger control freak than Renoir. I think Verso's ending is the better one. It's incredibly sad to say goodbye to everyone we met along the way, but it is morally the better decision
