Absolutely loved the original game as a kid, and I love it even more as an adult.

The game feels the way it felt playing the original for the first time.
Even though I knew what was coming, some stuff still scared me, regeneradors still creeped me the hell out, and I still (yes, still) love Ashley.

There are a few minor gripes.
I hate the knife durability.
I get it, it makes sense for a survival horror, but I just hate that the canon is Leon with his pistol and ol' not-so-reliable knife that breaks constantly.
I found myself barely ever relying on my knife because of this.
I like the balance introduced with this: the bolt thrower, but it can be super annoying when a bolt goes through a fence and is permanently gone, so I just end up sticking to my other weapons.
Parrying is neat, but honestly on keyboard I couldn't find a great button that I liked using, so I ended up using my left-click to parry, which was an issue if I was ever aiming.

I like Ashley, but I was a smidge disappointed that she doesn't call me a pervert for aiming up ladders anymore.
But to counter that, she feels so much more like a human being that I like interacting with.
I love her new interactions with Leon, and I love how helpful she is.

But all these complaints are just really, really minor things that bugged me, this is still one of my favorite games of all time, and I guarantee I'll be playing it at least a dozen more times before RE5 gets remade.
In fact, this is the first time in a very long time that I've beaten a game and immediately started another playthrough.
