There's tons of reasons why different RE fans enjoy each RE game. I've been enjoying RE3 Remake a lot, I love the breakneck pacing, one and done encounter and area design, the characterization and writing, the design of this game overall is incredibly tight and lean.
If you're a diehard classic RE fan, I can understand the disappointment with RE3 Remake, but in general, RE3 Remake does not fail at what it sets out to do design wise.
It's the tightest and leanest action RE game at this point. No fat, no filler, experimentation is quick and nothing drags on at all. The pacing resembles a bullet train. Which, in classic RE is the case if you have the game memorized from top to bottom. It takes a while to get to that level too. RE3 Remake has fast pacing regardless of how knowledgeable you are of encounters ahead and area design.
I have no doubt RE8 is going to be survival horror in gameplay and mechanics, exploration, ect. I love what RE3 Remake is, and would love to see what RE4 would be like if given this same treatment.
