Eh, you know about mine. Let me tell you about my kids'. These are for
Quest, which I picked for them because they wanted to play D&D, Quest is easy to make D&D-flavored, and Quest is remarkably simpler than D&D. Every single check in the game is a flat d20 roll against a single results table: 11-20 is always a success, for example. At the same time, you still get character classes and varied, flavorful abilities.
My daughter (12)'s character was inspired by two things: she really likes cats and Dungeons & Dragons: Honor Among Thieves. (Great movie. My mom loved it, and she can't tell a dungeon from a dragon.) So her character is a
Naturalist (i.e. Druid) cat-person named Doric who can transform into other animals. Her equipment sheet includes such weapons as "a lute" and "literally Xenk's sword." (The game lets you start with any three nonmagical weapons. I did not add Xenk's sword to my campaign.)
My son (14)'s character is a six-foot snake
Doctor with wings. Why a snake? I have no idea, but his lack of hands has become an issue multiple times. Why wings? Probably because they're cool, but a flying character with ranged attacks is A Problem, so we ruled that he could only hover a few inches off the ground.
The best character moment in the campaign so far came from a murder mystery session. A dude named Jean-Pierre owned an owlbear named Albert (get it?) who had been accused of murdering a child in the town, and the rest of the town wanted to put Albert down. The party was able to confirm that the owlbear did indeed maul the kid. Everyone else was ready to call it a wrap, but Doric believed in Albert, and she insisted that they continue investigating. They eventually learned that the kid had been given honey made with the extremely rare moonflower pollen, which drives owlbears into a berserk rage, by Beatrice the beekeeper, who had a grudge against Jean-Pierre and Albert. Doric was vindicated, Albert was spared, and Jean-Pierre learned an important lesson about pet ownership, all because my daughter refused to accept Albert's guilt.
