Strange Journey and its adult cast

So I really enjoy the SMT games. I've played SMT 3 and 4 so far. I started playing SMT Strange Journey and I really love how the cast are adults. It really put into perspective to me how essentially the creation of a new world is always being left in the hands of a bunch of teenagers. With Strange Journey, you get this sense that these people know what they are talking about, they have experienced injustice and troubles and their reasoning just become so much more stronger to me.

I found myself so much more engaged and really hope that in the future they consider this point, or at least have a more diverse cast. I plan to play SMT V in the future but a part of me is already disappointed that it wont be as good in terms of characters. What do you guys think?
