Except episodic games are just so you can ooze more cash out of an otherwise incomplete narrative (cough, imo). I don't like paying ten bucks per episode for an otherwise complete experience.
BP splits its narrative 3 Acts between with War in Heaven but I won't call them "episodic", because in those same acts you have several chapters (?) and story arcs going on within, plus, y'know, Tenebra is different narratively and gameplay wise. "
Acts" imply there's several chapters within, or at least that's how I grew up understanding Acts from Chapters depending on what video game was tossing the term around.
