Is it weird that I think of Halo 3: ODST as one of the real detective games? Not because it’s particularly dedicated to being that, but because the default ending of the game is that you don’t solve the mystery and leave unsatisfied. You’re just some grunt and what’s actually going on is above your paygrade. Learning the truth is a bit of a pain in this ass but it’s also basically half of the game’s story. I think it was a really ballsy move for what it’s worth.
