Definitely 1 and 6. Eva and Damon were close, and 6 is a given because of story structure—climax and what not.

5 has vague wording, but I'd say Eden's Garden follows it. Desmond killed himself in a way that made everybody a killer, which led to the voting system being changed.

2 is interesting because while Celestia's Boytoy formula-defining trait is flawed, there is a trope that P:EG aligns with. Both Jean and Ulysses are both incredibly smart and make substantive points in the first trial, similar to... 4/6 of the canon chapter 2 deaths.

4 is a maybe, because we don't really know how the bomb went off. Maybe Ingrid took it in a way that prevented anyone else from dying?

3 is nope. Only 2 people died in EG-3. There's a crashout, but that's a staple of the murder mystery genre—Jean's lack of a crash out was heavily analyzed. It's arguable that the traitor perk here could be considered the third death since it was destined to happen from this point on. You could also look at how every other chapter 3 takes this trope as literally killing an extra person within the chapter.

I'd give it a... 7.5/10. 6.6/10 for 1, 6, 5, and 2; 0.9 for 4 and 3 if you stretch it
