Not to mention we're really not giving a good reason to root or sympathize for Nadine. It sort of predates the problem with Abby. Like I mentioned back in the V1 thread, it should have just been Chloe and Cutter. That would have been more interesting. The only other advantage Lost Legacy has that it's a better Tomb Raider game than the reboot trilogy.
I don't know if that would've been more interesting, since they already know eachother and are pretty much pals. The whole set-up with Chloe and Nadine is that they don't know/trust eachother yet, and they don't really get along. This can actually be a very effective character dynamic. I actually like that we have two people from Drake's past - one an ally, the other an enemy - teaming up for a mission. It holds a lot of promise for some very fun and interesting interactions, and in the opening sequence I think it works pretty well. It's after that that I think things kinda collapse between these two, but that might also have to do the free-roam structure of the middle portion of the game, in which many of the areas Nadine isn't even with you and just sits in the car.
The game also doesn't seem to know how to characterize Nadine outside of her villain role. She worked well enough as the secondary villain/muscle in
U4, as
Uncharted villains go, but as a hero/ally it feels the writers were a bit confused on what to do with her. They gave her this trait where she throws out animal trivia, but it comes across a little forced. Like the coin collecting with Abby in
TLoU2.
As for Abby, I think the biggest problem with her is that she's not Ellie. Eventhough Ellie in
TLoU2 sucks (writing wise), she's still the character that we have history with. So any character that replaces her within the same game is going to feel like an intruder. There was plenty for me to root for and sympethize with Abby eventually, but because we know we were playing as Ellie, and would likely return to playing as Ellie, Abby just kinda felt like a place holder. Her rushed history and her being the daughter of some npc we didn't give a shit about also didn't help. Had they given Abby a connection to Marlene, her tragic past would've at least had a face and a personality we were familiar with, rather then quickly trying to flesh out that surgeon guy.
