Resident Evil 7 is more riddle filled and slow paced with an ability to fight back your enemies. Outlast 2 is more dynamic and is more of a hide and seek game, which is not bad. In terms of horror I think Outlast 2 has better Horror Elements. Resident Evil 7 didn't really shock me. It scared me, yes. But I think a game with some shock elements gives it more personality (See: Dick-Cutting-Guy in Outlast 1).
