I love Christie, and I'm always interested in adaptations of her work. I normally wait for games like this to get a price cut, but I couldn't resist. I haven't played very far into the game yet, but I'm enjoying it. The plot and characters of the first case feel like a Christie short story from the 20s or 30s, so I think the developers do actually know the source material. The presentation is nice and polished. The mind maps and evidence gathering remind me a little of the Phoenix Wright series. Judging by the number of "Collectables" in the menu, it looks like there's going to be plenty of content.
