There are three different streams at the get-go - 3 ways to get to the Precinct which do divide you into three [I don't have words] plot trees / plot floats?
Give you the same basic scenario - the victim, the reports, the suspects (or most of) and some of the interviews (but your interpretation could be very different)
Give you different quirks
[Plot 1 is yet to develop its own quirk beyond stealing a motorbike]
[Plot 3 is for the Episodic fans - extremely weird]
[Plot 2 is more crime / whodunnit/ procedural - closed to a real dS episode]
