Well, if you have played the demo, I don't understand what did you expected to RE6; reading someone here, demo was infinitely worse of the whole game.
This one's tricky. After playing the demo I was optimistic for Leon's story, a little less for Chris', and even less for Jake's. However, I don't really play demos and throw the stamp down. It's a demo. I thought it had some good elements in it and I was intrigued to play more to see where it went. That, and I'm admittedly a very optimistic person-- it's just how I roll. I like to enjoy things and I like having a positive attitude. Regardless, I won't sugar coat what I think about something. Some may think I do, but that's for them to decide I guess.
However, the overall game presented so many more problems than what were present in the demo. My main beef? Just like with RE4 and RE5, I didn't get any trace of "Resident Evil" out of it. That's my biggest, chief complaint right there. Here's how I do things: if I grow to love something, it's for a reason. The reasons why I used to love the franchise were wiped clean after Code: Veronica. I haven't played a Resident Evil game since then-- and that shit was over a decade ago.
It's not so much about the controls or the emphasis on action-- I've always felt that the RE games had an abundance of action, and they've always had these cheesy b-movie type stories. For me, therein lies some of the charm. RE for me has always been about that, being lost in environments while trying to solve puzzles and fend off zany creations that stand between me and the Pearl Key which will lead me to the Elephant Tusk that I need to unlock the door to the .357 magnum so I can blow a tyrant out of a fucking airplane. I love it.
RE6 is a menagerie of fatal game design decisions that, outside of the zombie window dressing and the occasional cool RE-ish type creature, contain zero elements of why and how the series originally became popular. It's true that RE4 brought a lot of popularity back to it, and that's because it's a well designed game. A lot of people didn't care that it lacked some of the "essentials." That's fair. It's fun as hell, has a load of content, does have its atmosphere here and there, etc. However, I didn't see it as an RE game and I sure as fuck do not see 6 as an RE game. I don't even know what 6 is. 6 doesn't even know what 6 is.
