You make good points. I still prefer the game over remake cause remake's art style is quite dull. All remake has is lisa trevor which ı wished appeared in re0 instead of remake. I dont mind it not being connected to remake since remake when compared to re0 and re4, seems to be a lot less serious release due to mikami directing it without iwao being in charge unlike re0 which he didnt direct and re4 had all those messy prototype builds which seem to have different directors before mikami was chosen for the final one. Though re0 still gets hurted by gamecube deal more than remake and re4 imo which seem to be more popular releases.I recently had a huge session with Zero again, played through it roughly five times on PC. I have to say it's odd, it's a game that never really lands in my top spots but when I break it down, it has almost every element from a golden era of Biohazard that I love. It's quite literally REmake engine wise, visually, artistically and general gameplay. It had some oddities to it, but I feel like I was tougher on it back then because of the standards the series set. Looking at it now, it really has so many elements that make me fall in love with a Biohazard title. Great music to boot. I'd say how disjointed it felt from REmake despite being a prequel is what rubs me the wrong way still, but I'm willing to look passed that given how many other aspects it lands.
For gameplay; ı like it more than remake, even more so with the unlockables, my favourite being magnum revolver with infinite ammo unlockable. That thing is quite fun to use imo. Remake doesnt have interesting unlockables compared to re1's many ports and re0. I also find the burning corpse mechanic boring while ı like killing mimicry marcuses with fire.
I would say my favourite aspects about re0 are rebecca and billy teaming up, wesker and birkin cameos, marcus and his leeches, t-001, queen leech fights at the end as well as unlockables. Worst aspects imo are inventory management, hookshot which takes 2 spaces along with multiple usage as well as that giant bat which feels awkwardly designed.
