Yes the hero stuff is very cheesy.
I also find it odd that only Jill got infected with a virus (which was cured) despite everyone having close encounters with zombies.
Unless you count Leon and Ashley's plaga infection.
I do have a strong feeling that at least one character will die in re6. 7main characters in a game, and no deaths would seem really "too good to be true"
Then again, that's like saying why do bad guys who have amazing aim in films always miss the main characters lol.
The gameplay mechanics have gotten better, the storyline seems to have gotten weaker though as well as the lack of puzzles.
They are still fun games.
My only regret is that I havnt played re zero or any outbreak games
Oh and in terms of scariness, I think people in general are much harder to scare these days anyway so it's hard for a game to aim for your fears without becoming rediculous.
