Not smart, realistic (even if you assume the technology is possible) or guessable, but logical. The final explanation is interesting and logical. This story is really good, it's engaging and you want to understand everything that's going on, which makes you keep going. This is the best adult VN I've ever played. Now I've been overly negative there with my main criticism so let me back up a little bit. Now there is one very cool twist which they do pretty well, in my opinion, and I guess lots of people would call it the main or at least most important one, but this barely makes up for all the other explanations for everything they give towards the end, of which there was absolutely no possibility of working out or even many hints and foreshadowing to notice the second time you play it. I can't really go into detail without giving away spoilers, but in general a SMART storyline gives you a chance to guess the ending, and any twists along the way, before you reach it. Because while it is entertaining, and there are some cool twists, I'm very hesitant to call the storyline smart. I'm not saying you shouldn't get this game, because you should, especially if you like extreme stuff, I'm just saying it's no Code Geass. Yes it's good, but let's not get carried away. I'm not sure I agree with others who seem to be claiming this is the best storyline ever written in an adult VN.
