The magic of this game finally hit me at Episode 4.
Episode 1 I was intrigued.
Episode 2 it started to be too simple, so I rushed through it. Not enough happens.
Episode 3 I fell in love with the additional mechanics, but unintentionally began spending way too much time accomplishing too little. I started to lose interest here but the end with Fragile... Great shit.
Episode 4 was incredibly cool, they must have spent a lot of time working on it's short but sweet features.
Episode 5 starting now, still equally interested. Went from disinterest in Mama to very interested in her. Really loving the stream of new items and abilities.
I don't think anyone should waste time with the side content in this game, just stick with the main story. Unlike MGSV in which side missions were a blast due to the emergent game design, that emergent game design doesn't quite hit its mark in Death Stranding.
