Resident Evil 7...
Holy shit! Scariest game in the series by far. It's definitely the new RE4 in the sense that it marks a departure from the previous gameplay style and also happens to be a very well made game to boot. On the other hand, it almost feels more like a new IP. Then again, RE4 probably would have too if it wasn't for Leon and Ada being in it. Yeah, I really miss Spencer Mansion and Raccoon City, and the whole atmosphere of the original trilogy, but on the other hand that couldn't have gone on forever without losing steam eventually. It's better to remember it as fondly as most fans do. Same goes for the original cast. You can only go on for so long without everything becoming a mess like RE6.
That being said, this just isn't a game for me. Way too scary. The classic RE games were campy and felt like a tribute to horror themed "so bad they're good" b-movies. This game feels much more like a legit scary and modern blockbuster horror flick in comparison. But even if it's not for me, I'm still able to tell this is definitely a first class production.
