RE6 to me is the last "true" game in the mainline series, or Revelations 2. They have that RE something to them, despite being bashed a lot online. There's also potential to have Alex Wesker as a main villain, although I have a funny vibe that Capcom just doesn't care.
7 and 8 are some Addams Family Values bull crap. Those games are just ridiculous, have a story retcon I hate, and Ethan Winters does nothing for me, nor the awful gameplay and dark, bleached out backdrops. However, I do think using new protagonists at this point in time is somewhat important, because they always wanna use the same beefed up male heroes, and even the women are more than capable. This to me takes away the horror, and feeling of being vulnerable. I understand RE has combined different genres, so the style is changing a lot. But I like my horror to be like Silent Hill 2, where some person just visits a place for to look for someone, monsters show up, and the main character is overwhelmed.
