On the issue of region linearity, if you look at the games nowadays, you'll notice that they're constantly pointing out to you where you're supposed to be going, so the idea of having a linear region is kind of redundant in that regard. So I was thinking, what if they could take advantage of this to help less skilled players? On that note, I have an idea that could solve this linearity issue once and for all. What if they had some kind of Key Item like the Fame Checker that records conversations relevant to the storyline? Then whenever you get stuck, you could use it and it would give you a hint as to where to go next? For instance, if it were in BW2, it could record your conversation with Professor Juniper about her wanting you to talk to Drayden in Opelucid City. From there, all it would take is a quick look at the map to figure out how to get to Opelucid City and then you know exactly where you need to go. They could also do the same thing with sidequests, although hints toward sidequests would be in a separate section since they're not important towards the storyline.
