Already blew through 5 episodes and so fast that forgot to take screencaps. Yeah, ACCA turned out to be everything that I wanted it to be. It's imaginative and different. There were series where various factions maneuvered, but not at this level, at least recently — I have to reach back to Manabi Straight and Legend of Galactic Heroes to a reference.
Not everything is top notch, of course. The cigarette thing is overwrought, IMHO. Regions are much too cartoony in their characteristics. In particular, the isolated district is bogus, although possibly less so for someone who internalized the pre-Meiji Japan. Even North Korea has cellphone service nowadays. But I don't have any beef with the main idea and its execution.
