Okay - so I got into this game last night. I only played the 'Leon' path so far, so that is the only one I know about so far. Without spoilers, I will do my best to describe the experience.
1 - There is definitely a different feel to this game, and I really like it. It reminds me of the early games, without actually being the old style of gameplay. I think a large part of this is because of the use of atmosphere. In RE5, there was a whole lot of daylight, and as much as monsters can come out in the day, night is so much better. They also did a great job of the nighttime lighting in 6. It's very realistic, as in my eyes had to adjust at some points, just to see that, oh yeah, there's a zombie there waiting for me to step on it. There are a lot of scenes where flashlights are used (headstrap lights too), and it really does matter. It's a more frightening atmosphere, when you know there are things there, and might be closer than you thought, but just couldn't see them. So far, Leon's path really does remind me of the old games, and that is a welcome surprise to me.
2 - Not all of it is great. There are a lot of Quicktime events. I'm not a huge fan of this, but as long as it doesn't become too overbearing, I'll deal. Something that bugged the SHIT out of me: I was walking along, being careful, and I spotted a zombie sitting up on a stool. Now, my experience with this type of game tells me that that fucker is going to get up, and come after me when I least expect it. My response? I shot him in the head before he could. Then I shot him again. And one last time just to confirm what I was seeing. And it was terribly disappointing. The problem is that until they have been triggered to WAKE UP, there's no damaging them. That is a big pile of steaming horseshit as far as I'm concerned. I should be able to put slugs in brains to keep them from getting up, if I so choose to play that way. BIG MISS in my eyes.
3 - The storytelling is kind of disjointed. I won't give anything away, in case anyone is like me, and you play the games for the story. What I will say, is that it's kind of like they took notes on movies like Pulp Fiction, and anything written by Guy Ritchie, and said, "FUCK YES, that's what we are doing!" Mind you, that doesn't have to be a bad thing, and another thing to note is that I'm not all the way through this path yet, so it could get better. I'm waiting for it to, because I feel like I'm being made to think like an ADD squirrel on crack at the moment. This is a preference thing, so others might enjoy the style. I will say this about it, it feels like playing a movie instead of a game at times. Take that as you will for whether or not that's a positive.
4 - The most important thing of all. I'm having fun with RE again. There's really no getting around that as a result. So far, it's enjoyable. I already like it better than 4 and 5, put together, and I really am having a good time. That makes it a worthwhile purchase to me. And I honestly never thought I would say it, but Capcom did a good job.
