From eldest to youngest (IMO, played since Gamecube release)
Cranky--They range from a very rugged 30-something--to anything above. I think most of them are
30-55 years old. I think Lobo is 33-35, and Wart Jr is 50-70.
Snooty--Anything from
25-50, some like Broffina are immature/bitter/judgemental
40-60-somethings, and I see Freya as a very mature, sweet 30 year old, she may even be 28.
Just she is one of those late-20-30 with the mind of a 50+ year old.
Normal--They are mothers, homemakers. I think they are
35-40 years old on average, but I feel Marina may just be a bit of
a sweet, but stuffy/overly sensible person in her late 20's.
Uchi-- Phoebe & Muffy remind me of people I know in the
25-35 range.
Young at heart, but not actually teenagers. They have a protective, comical, that-crazy-auntie vibe about them.
I think there is a lot of motherly/big sister wisdom in their actions, and they are like that person in thier
late-20's to 30's who really wants to stay cool & hip.
I feel like Muffy is 24-30, and Phoebe might be anywhere between 25-33.
Smugs- Definitely around
30 some could be younger, but in general they strike me as a charming, slightly young at heart male who is 30, but has the occasional insecurities of a teenager, but romantic streak & philosopy of a 30-40 something male.
Youngest I'd say is 20-something, but that's a stretch.
Jocks & Peppy-
15-25 Some may be older, but that's an average.
Lazy 10-22 Some seem like small children that still have/need parents looking after them, some like laid-back young adults that are just sweet & innocent.
