Hi! Thematically, A Distant Plain covers with the detail of the entire game what is happening in just one space of LABYRINTH.
So could it be said that thematically, ADP is to LAB as 1989 is to TS. That is, ADP and 1989 cover in detail specific moments which LAB and TS cover in brief, broad strokes.
Regarding gameplay, they are entirely different systems.
