I just think the story was incredibly exhausting, in the best possible ways.
We go through so many ups and downs with the characters, and the adventure, along with the context of the game's world, makes it hard to believe that Ellie and Joel would have another continent-trotting adventure.
What exactly would be the story? It's difficult for people to think of one, and people are happier thinking they lived relatively quiet lives after going through such a harrowing experience. It's not to say that I dont trust ND... but I just don't know if I want to see the characters retread old ground, and wonder what new adventure could create some new experiences that evolves the characters any further. We've seen it all and really well: Ellie and Joel grow close, they grow awkwardly, they fight, Ellie runs away, Joel saves her life, Ellie gets assaulted... those are huge events that seem to stretch the story a lot. I'm wondering what else could possibly be done.
I want new characters and a new place because I think ND did a great job of unfolding such an apocalyptic pandemic. I love the eerie quiet lifestyle of Joel, how the small town he lived in didn't know what was going on...the beginning was so great.
I'd love a game that takes place shortly after the breakout of the infection, in a place where we can see a different diversity of clickers.
I also am so interested in the characters they create that I dont want to see another Joel/Ellie. I want to know what they can do next. Henry and Sam were awesome, for example. As was Ish. I'd love to play someone else, because I want to see what ND can come up with.
