I thought at first that Aria would be Isaac's counterpart and make them enemies of some sort, while at the end becoming close friends, but then I thought people would overlook her and still go for Isaac nevertheless, so I thought a bit more and decided that they should be twins, this sole fact would push the cooperation and estimation of them both as protagonists of a game instead of a protagonist and co-protagonist.

Seriously, at first, I was thinking Aria would be a risky choice, but I didn't had any other better idea to make my storyline, and I don't regret this choice either, now I think she was what I missed on my game, because seriously, after a while, the old storyline was a mess and quite pointless in the end.

As for the metropolis, I was thinking of the title and eventually came out with them building their own city in their world for the reasons already explained above, I think this newly implemented content opens a very wide world of new content (as well as for a lot of DLC and extra content), we are grazing the top of the city without going to deep on it right now, I am planning for this city to be the main attraction of the extra story (as well as for the rest of the game's course).

I don't recall if you noticed, but the main story is actually like a huge introduction, while the extra story is where the fun starts.
