I only use the d-pad for classic RE styed games. Might just be my nostalgia playing since I grew up on RE2.
I must highly disagree with everything else you said.
Maybe the lighting/aliasing is off with the HD version then. You can't alter the brightness in game and I didn't want to touch my TV for it, but I literally could not see a single fragment of several items in corners and alongside walls. Seemed weird.
I played and beat RE0 yesterday, probably burned through 80% of it in a day. I guess you had some item box troubles in the other games pierrot, but well you will definitely miss them here. This is still my biggest complaint with Zero, they took out item boxes. Instead the game lets you drop items down to the floor, but any given room can only hold 8-10 items or so. So, yes, no more linked access to your stored away items. Wherever you drop something is obviously the only place it's ever going to be.
My first time through Zero I didn't realize that later on in the game you'd have the ability to easily backtrack throughout most of the game to more easily grab items you might have stored away somewhere... So the further I got into the game and away from the big two mansion-entrance like areas that I treated as my main item hub rooms, I was constantly sending my characters back and forth to transfer items around. That was a massive mistake and made my first experience pretty sour... so this time I didn't bother, and rarely even picked up herbs too. Dropped items are marked on the map and if you examine items but don't pick them up, they are then marked (with an extra sparkle to see them in game better), so I just did this with herbs to mark them.
If anyone here is playing Zero (noise?) or others considering it, definitely take that advice ... try not to hoarde the items around too much or keep them too organized, it'll just give you a headache in the long run.
In Zero, the grenade launcher also takes up two slots. As does the hookshot which you have to lug around at times. Luckily I knew when and where I needed that.
Like I joked earlier the game is extremely brown too. I'm not a fan of the train prologue level either. So it's kind of so-so in the level design department.
tl;dr I didn't love Zero my first time through, but it was more fun a second time around knowing some things about it ahead of time, that made another experience a lot better. Rebecca is awesome and Billy is one of the better random one shot characters thrown in for whatever reason, and it's cool to see more Wesker and Birkin plotting behind the scenes. The story is otherwise pretty whatever though with a laughable antagonist and ending, but yeah solid stuff. I like it more than CV for sure.
The plot is very bare bones in RE3, but the classic vibes and fun factor still remains there for me, so I'd still take that one over RE0 and CV. RE1/REmake and RE2 completely blow those out of the water for me though, those are perfection to me.
I also got the RE5 platinum for the PS4 haha. It wasn't that bad. Sunk 23 hours into it to finish up all the difficulties. I still think it's an incredible game and gets wrongly slammed. Now I'm blasting through RE4 HD and loving it again too. Easy to just say that RE1/REmake/RE2 and RE4/RE5 are my favorites, two sides (survival/adventure and then action) of the series that did their respective focus best in my opinion.
