I found this just a few days ago, and it is great! I was about to suggest you do Seeder (as a 12-year old) or Chaff (as an 18 year-old).
And also as an idea for an up coming arena could be mountains with a bunch of lochs randomly placed between them and Loch Ness sort of Monster Mutts that would eat you if you stayed there to long. This would be basically inspired by Scotland lol.
You don't have to use this tdea but I hope you do :D, this fanfiction is great!

Hey I've just finished reading chapter 10. I Love your stories, you're really creativ, I'm really impressed at all the differnt angles you take for each victor and enjoy seeing the friendship between them all. Ive loved the idea of of taming mutts and getting a horse as a sponsor gift Ive been craving hunger games content and yours is great. Keep up the good work.

Great work! Loved the story, especially from Snow's POV!

I really liked this...thank the victors, Crystal was like Franc and not the other cronies. My only suggestion would be that, try making the paragraphs shorter, and give more breaks between them. Legibility and readability improves that way.
Amazing stuff

UGH! Not another career, please! But this chapter was amazing...the background you gave, and the bond between Ford and the citizens from six...it melted my heart!
Beautiful writing!

Great job! Loved it! Switch, baby!

That's all I have to say! Enjoyed this to the core!

THIS WAS BY FAR YOUR BEST CHAPTER! LOVE LOVE LOVED IT!

Ahhh...tbh, the chapter was cool, but there were certain grammatical and spelling errors...maybe proofread a bit more? That was all...I honestly liked the chapter! :)

I especially liked this chapter! I'm hooked!

No bad paragraphing! I actually really enjoyed this chapter! Well written!

This was really well written! I love your stuff dude!

The series is amazing! I love it so much, dude!

Idea, maybe make the next arena like idk a beach? The ocean could be full of mutts and then across the ocean there are mountains also in the ocean there are various small islands.

I have really been enjoying your series! You have made all of your Victors quite different, and I love how you've been not only focusing on the Games, but adding information of the rebellion and the Capitol! My favourite Victors are probably Axel and Woof, and I'd say this is my favourite arena so far. Keep up the great work!
