Killzone: Shadow Fall was a pretty damn terrible game, with its shiny graphics being a distraction from its mediocre design in all other respects for only so long, but it did do one thing very, very right: it had an excellent feedback system built right into it, called the Killzone Player Voice, and of course, there are now players curious if that concept will ever be revisited in the future, at least in any other games Guerrilla might make.
The answer? Yes, they are looking at including something like Killzone Player Voice in their other games, the developers said on the Killzone 10th Anniversary livestream, where they said that it was all hugely beneficial for them, especially since it gave them a finger on the pulse of the community and what the community felt was important, letting them prioritize accordingly.
Hopefully, they are also using that feedback system to get some better game designers in place- in technical terms, these guys are amazingly talented. In terms of actual game design? Not so much.
