I haven't played Heavy Rain, but I watched a playthrough, and HR is clearly the better game.

I'm playing L.A. Noire right now, for the second time. Why would I do this? Because I thought I didn't give it enough of a chance the first time around. I beat it and it left a bitter taste.

L.A. Noire is just... frustrating. I realize how much I lOVE the investigation aspect, but the interrogation/Truth/Doubt/Lie system is one of the worst things I've ever seen in a game. Ever.

It just makes every witness and interrogation so problematic and frustrating. The looping face animations don't help either, especially when someone is lying and staring right at you, not moving or twitching at all. Their face expressionless, just straight.

How does the game expect you to read faces when they pull ♥♥♥♥ like that (and most people playing know nothing about reading faces in the first place)?

It comes down to a guessing game rather than any thinking at all. Not to mention that the game "lies". It tells you that the investigation music ends when you investigate all the clues. I stuck with this, picked up everything I can, investigated everything, making sure that the music ended each time, yet I'd still get a missing clue or two from the tally at the end of the case.
