WHAT AGE RANGE ARE THE CHARACTERS IN YOUR GAMES?

The characters in my games have tended to have ages that tend to match my own age when I started them.
Mimi So&so (yes, that is her actual last name) was somewhere around 13-15ish back in Mimi's Mountain. I wasn't exactly that skilled in writing back when I was moving from middle school to high school so I never really factored in how messed up she should have been from her backstory where she had went on a precious adventure when she was just a child to rescue her father and kill Antwan the evillian and then during the game story proper had to deal with her best friend being kidnapped, as well as Antwan's ghost still lurking for revenge. That is, until I wrote a reinterpretation of her story in Creeptacular Shack, which is a modern horror au which takes place presumably on earth instead of Thirdinaltup. In that one, she's 16 years old and constantly wracked with guilt and anxiety.

In Jello and the Valley of Duh, Jello Purin is 16 and lives by herself due to Plot Reasons which were written more as an afterthought of thinking "wait, where are her parents, she's still a teenager!". Kirby is stated to be 200 something years old, having spent most of it eating and sleeping, and emotionally about 13 years old, as opposed to how babylike he was depicted in the anime. Raiblu is roughly 17 or something, and had to grow up fast due to hardships in his past, hence why he's fully evolved and barely knows any high level moves.

Seth is a bit of a special case, considering he was first written as 13 when he first appeared in SBARGv2 and then was aged up in real-time due to being a character in an ongoing chat based rp. At the time of Sethstuck's development, he was almost 18, give or take any time shenanigans that would have made him older or younger than a simple calculation from "birth date" would add up to. All other characters in the underworld part of the game are younger dead versions of Seth, locked at their various states of (im)maturity for eternity, youngest version being 13 years old due to being hit by a meteor without the knowledge needed to avoid it.
Being written exactly two years after Sethstuck, Just in Time features Seth at almost 20, and shows hints of him being just a little more mature, especially concerning the knowledge of how easy he and his new battle partner could die despite his godtier status (it's ambiguous whether or not Justin had ascended to godtier but it's assumed that he never reached that point in his session), but still capable of making the same sorts of rash mistakes he would have before. I have no idea how young Justin is supposed to be, but I'd guess probably a bit younger than Seth due to his sheer lack of experience with his time powers.

As for Coda from A Snowball's Chance, she's a rough self insert so she's firmly 25, but tends to be a bit immature and unseasoned to the outside world due to her conditions and circumstances. Her hiking group is roughly within the same range, with Vern being 26 and Topaz being 24ish. They all have day-jobs that they're taking a break from for the week (cook at a diner, stage actor, bodyguard). Frie however is a complete mystery, as she is an outcast from society and is also a type of dragon person. Considering my gamedev partner wrote her as her own rough self insert, I'd say Frie could be somewhere around 17 or so.

So far, Coda is the oldest main character I've ever seriously written for. I'd definitely have to chalk it up to not knowing how to write adults and sorta feeling like I don't know much about adulthood in general. Similar age/a couple years younger is definitely easier to write for and relate to personally.
