Developer Supermassive Games have been doing the choice-driven horror thing for a while now, but it sounds like their upcoming full-price standalone game The Quarry will push things to a new level. In a recent interview with IGN, The Quarry director Will Byles reveals the game has a 1000-page script (or the length of about 10 movie scripts) with well over 100 different possible endings for its characters.
