This is where I began my chronological journey to RE. So I played it before RE1. And the thing about it is if you play 0 after 1 it would make it look secondary (which it's kinda is), and if you start with 0 RE1 would have some annoyances.
RE0 is a game of "buts" in almost every aspect. It looks nice and have great ost, but after that: story is good, but unnecessary; characters are interesting, but a bit primitive, also Rebecca is not really consistent with RE1, and no one saw Billy since that day; puzzles are mostly interesting, but almost all of them based on the fact that we control 2 characters, also when you do not know what you will need you will have a bad time backtracking, I'm a big fan of drop mechanic, but hookshot, takes 2 slots used in the beginning once and 3 times in the end; nice locations, but "yet another mansion"; enemies are boring.
In the end it is my favorite "classic" Resident evil but not everyone will like it, because of it's secondary nature, with too little upgrades over RE1.
