I haven't been able to stop thinking about this game since I got it over a year ago. Not a constant thinking, but every so often I run through it all in my mind again. I've certainly spent more time thinking about it than it took me to finish the thing, in any case.

A perfect game. I haven't really been able to play any others of the genre (calling it a "walking sim" isn't true but gets you in the right ballpark; it is very literally a "role-playing game" but isn't what you think when you hear those words) since. The only good dialogue system in a video game.
