This is pretty cool!
I haven't ever thought of a Fire Emblem themed Hunger Games before, but the idea works. I have tried it recently using a different set of Fire Emblem: Fates Characters before, and it was really cool.
But there are some weird things I don't like about the Simulator:
1. First of all, almost every time I simulate it, there is always a time where one character makes another choose to kill someone from a choice of 2 characters. The person always refuses, so they get killed instead.
2. I also hate how fast the characters die. Sometimes the game is over on Day 4, but I've gotten a simulator go up to Day 8 with Corrin M, Azura, and Felicia. One time I did the simulator and (I don't really know what to think of this) but when the games started, the first action out of every player was: "Camila falls into a frozen lake and drowns." lol. When the arena event comes around, half the characters die.
3. I'm not a big fan of when three people are fighting, and one person runs away while the other person dies. Why would they do that? Wouldn't they try to fight?
Okay, I'm done rambling about the bad parts of the simulator, but there are funny parts of it.
Like when an unlikely group of characters team up/help each other. (I have had Lucina and Henry cuddle with each other, but the next day was the arena event with the monkeys, and when Lucina fell, she dragged Henry down too, and they died together).
Thanks for sharing this, meant to comment on this yesterday!
