This is a good point, but while playing the remake, I couldn't help but wonder how SE would handle balancing the progression of materia & weapons for future iterations of the game. Like, we haven't even left Midgar and it's very likely that most people have already mastered significant portions of their materia, even with little grinding. Will Part 2 have players starting completely from scratch, or will they be able to continue using their level 50 characters? If they go with the former, will they throw in another plot device like time demons to try to explain the change, or will people just have to deal with the ludonarrative dissonance?
I think a lot of this goes back to the problem pointed out earlier, that this seemed to be a stand-alone experience rather than a piece of a fully thought out, episodic one. That being said, I absolutely loved the game, but I'd be lying if I said there weren't also parts that I absolutely hated.
