Honestly, I kind of expected that from fairly early on. From how much they were revealing, and what sort of information they were choosing to tell us, I sort of got the feeling that we were going to have a lot of unused potential in things like the world and setting. Which sucks, because I doubt we'll see it expanded upon in a sequel or anything.
I'd probably have finished by now if I wasn't trying my utmost to complete all the challenges as I go. Stupid things restricting your abilities and giving you timers. Planning challenges are by far the best.
