Censors: expected, except the Viet Cong/commie thing. Is that something that can't even be mentioned? Or just referred to negatively?
Blood: confusing. Did they just go with one or two floor splatter patterns, mop up everything else, and call it good?
Details: can't track all of that because I'm a disgusting phoneposter, but one thing I could forgive there is mirroring lights on a couple of the floors (unless the grocery floor is meant to look soaked). More importantly, how on earth does the game need 32 TIMES MORE MEMORY?
Difficulty: it sounds like the only big problem before was the save/time system. Sad to see the number of "fixes" made that weren't needed. It likely contributed to the other buggy collision problems seen elsewhere.
Voices: I swear, they must have had the actors try to match the pitch and pace of the originals to avoid completely reanimating cutscenes. It's so weird, and would be a very Japanese/autistic thing to be concerned about.
