I really enjoyed the change in gen V, where the Protags were 16, instead of 10.
It made far more sense plot-wise and allowed the characterdesigns to look more mature.
Also you don't feel as weird anymore calling the femMC hot.

But how old are Calem and Serena?
Their game-designs do look like they're around 16-18, but your friends feel more like 12-14.
The anime Serena looks like she's an 8 year old that likes to dress like a grown-up.
Is there any official word on this?
