You (and anyone involved) did an absolutely fantastic job with her so far. She is literally the cutest thing. You guys may have actually created a "monster" of sorts with her because despite how great the rest of the game is, I think I'm looking forwards to more Chloe-time than anything else right now.
And
Oddjob404, I'm sure most people feel the same as you about kids being involved in these games, I'm normally the same way. It's an incredibly risky idea for a dev/team to go anywhere near this kind of thing, kind of like handling an unexploded mine, but in this case I feel it was done so well and that she's so adorable and wholesome that it adds a lot to the game and to the MC's character development.
The whole "I have to get a job, I have to get money, I have to get back what I lost, blah blah blah" character building gains SO much more weight with Chloe. It's no longer a case of the MC having what might be called purely "selfish" desires of "getting back on top so he can fuck dem bitches" or just "getting his life back together". Now it's "I have to do this for Chloe, I let her down, I can't ever do that again." In my opinion, the MC having that sort of motivation makes him far more likeable and relatable, especially for those of us in the "Fuck that Laura bitch" camp.
