Let's be honest about L.A. Noire.
I really don't see why L.A. Noire is praised as groundbreaking whereas Heavy Rain is criticized for "not being much of a game." Yes, that is a valid complaint to be laid against Heavy Rain (To an extent, however; the game isn't supposed to be an action game, and I feel as if a large amount of the people who criticize the game don't realize or understand that (Criticisms should be regarding how the game handles the important aspect that I'll mention at the end of this paragraph instead)), but it's
even moreso for L.A. Noire. The
bulk of
both of these games are conversation and investigative sequences, yet in L.A. Noire, everything is scripted to a ridiculous extent; at least you have a bit of control over what goes on, as well as (And this is incredibly important for these kinds of games)
choice and consequence in Heavy Rain.
I'm convinced the only reason L.A. Noire is loved and Heavy Rain isn't is because of the cookie-cutter poor man's GTA action sequenced spliced between the interviews to break up the game's pace ("Maybe if we dumb down this game even more, people will love it"). And that's not even mentioning the exterior elements; L.A. Noire was created as a tribute to film noir, but Heavy Rain does a much better job at being a neo-noir than L.A. Noire could ever hope to be (Especially in terms of lighting and visuals, but also in terms of the narrative and morally ambiguous and complex characterization).
Honestly, I don't see any reason why this game should be praised, or even played. If you want a game that is almost
entirely choice and consequence-backed conversation with a noir atmosphere, play Heavy Rain; if you want an open-world action game, play GTA (Or Read Dead Redemption).
