So I've watched some interviews with them and reading their bios so here is my ranking:
1-Christine: umm obviously haha. I love the kind of nerdy/quirky characters, and she also loves Settlers of Catan which is the best game ever so yeah, bonus points for Christine!
2-Joey: Joey seems like she'll be a lot of fun to watch! I love that she's different and also that she wants to unite the girls!
3-Jocasta: She seems very genuine, and i think for an "older" contestant she will really deliver!
4-Hayden: There is just something i like about Hayden, i don't really know what it is, but he seems like a much more likable Frank
5-Paola: She seems like she has a huge personality and will be a firecracker! Im hoping she can keep her mouth shut long enough to get into a good alliance.
6-Frankie: I think Frankie will be another one who will be fun to watch. He seems very genuine and I like his strategy going into the game
7-Victoia: She seems a little socially awkward, but it's endearing. I think that she may be in trouble early because she seems like she may have a bit of a short fuse and could be a little catty. I like her a lot though :)
8-Nicole: Nicole seems a little bland at first glance, but i think that she could actually do really well. I love that she is a super fan too!
9-Cody: I like Cody, he seems like he'll do well. He fell A LOT on my ranking because he lists Jeff as his favorite player because "he's a good person" ummmm yeah, someone never saw any of the live feeds! I expect Cody to be in there for a long time
10-Donny: Donny is just meh for me. His beard is gross but i appreciate his character. He does seem like he's a good person.
11-Amber:I like that she wants to form a girls alliance! She seems kind of bland to me though :/
12-Zach: He reminds me a lot of Dr. Will, but i don't like how cocky he is.
13-Derrick: Nobody cares that you're a cop. It doesn't make you a better game player or give you a huge advantage. It does not make you better than the other players, get over yourself.
14-Brittany: She is the only girl i really dislike. She seems a little fake to me and she is going to latch onto a strong guy, get ridden to the end and promptly disposed of at the jury.
15-Devin: A question for you all: Does Devin have a daughter? I am already sick of hearing about his daughter and i've probably only watched him for like 5 minutes. He's sooooo boring.
16-Caleb:Boring,Cocky, and misogynistic: he's a pig. I'm praying he gets last.
I think the casting crew did a great job with casting women, but fell really flat with the men. I want to see men with substance, not just good looks.
