I had a look at Nationstates a few years ago – interesting idea but I did get bored of it after a while due to it going through a few cycles for its questions. I was spotting the repetition coming in.
I’d guess the book would be better 🙂 Computer stuff tends to fall down because the game can only do as it’s programmed, whereas a book’s plot is completely up to the author and can therefore go in unexpected directions.
Will have to have a peek 🙂
