Murdered: Soul Suspect is an extremely easy and short game with linear gameplay and repetitive features and mechanics. The test is of problem solving and looking for clues (detective work in investigations) and avoiding and taking out the only enemies of the game – the demons, and that isn't all that difficult to do. The game is extremely forgiving with checkpoints (after each investigation, before and after each demon area) and there is no punishment for selecting the wrong option when focusing on clues or solving investigations, so you could just use trial and error, with no risk of missing any trophies that are story-related.
Trophies do not "stack" between formats. That means if you get all the trophies for the PS3 version, you'd still have to play through the game and do it all over again for the PS4 version, and the other way around.
The main weight of the trophies (and where you will spend most of of the gameplay) is through the many collectables placed across the streets of Salem and the various investigation areas, which mean lots of the trophies are missable. In addition, one of the areas – the Museum – is inaccessible after completing the investigation in the Judgment House area. Therefore it's a really good idea to go after all the collectables before completing all the investigations tied to the Museum – complete the first one to get the “ghost trains” moving so you can access all the collectables. Otherwise you'll have to start a whole new playthrough of the game to get any artifacts you missed from there.
You should therefore go after the collectables by areas in order: Apartments, Church, Police Department, Cemetery, Asylum, Museum, Church Revisited (second visit), Salem Streets, and finally Judgment House. There's a whooping 242 artifacts in total, covering memories and back-stories of characters, ghost stories, and the Salem Witch Trails. Each area has at least one ghost story-related trophy attached to a set of collectables, so in the process of grinding towards Collector All you'll get all of them as you go. There is no requirement to watch any of the ghost story “flashbacks” that are unlocked either, those trophies just pop when the set has been completed.
The collectables ARE cumulative (you could miss just one in a playthrough, go and get it in the second and get the Collector All trophy) however it's far easier, and quicker in the long run, to get all the collectables in one playthrough. HarryNinetyFour has made a fantastic collectibles guide which will easily guide you through every area and grab all the artifacts.
There are also a couple of side-investigations that will help fellow ghosts find peace, and these are missable since they don't directly affect any main story missions, and all but one are sort of hard to spot. However, these are all simple to solve, as it's just a case of finding clues and selecting the right option much like the story investigations.
I recommend one playthrough:
Step 1: Play through the game. Take the time to get every collectable along the way. Feel free to enjoy the story, cutscenes, and read through all the notes, or skip them if you want to rush to the Platinum. Once you've gotten the collectables, the end of the game itself isn't far away.
Step 2: Clean up/second playthrough if required. If you missed any artifacts or side-investigations, go back and get them. Shouldn't be needed if you follow this roadmap and the collectables guide.
