I'm getting close to the end now.
I'd say this game is like a high 7/10 if I'd have to rate it. There's a lot of successes and a lot of failures, and a lot of things I sort of don't know what to think of yet.
To preface, i turned off rumble and clue chimes and never used intuition, so I had to actually find things and examine things and put them together. The clues themselves are really only important as they apply to the way you interrogate people and call them out on their lies, which is the heart of the game's appealing structure. It IS appealing to find a clue, it IS appealing to put it together in the context of the crime and it IS fun to realize someone is lying and then, due to the way you interpreted the crime, nail them with the evidence you've found.
There's still structural issues with it though. They really needed more control over HOW you responded in the interrogation. Should have been more open ended than TRUE, DOUBT, LIE. Also, they really needed to retool how you responded during some selected answers. Sometimes you (Cole, I think?) responded so over the top if you chose even 'doubt' that it came off as forced. Like, one time he was chewing out a fifteen year old girl when I selected 'doubt' and I was like 'fucking jerk.'
But still, the foundation is in place. It works pretty decently.
The voice acting as well needs to be commended... the writing is wildly inconsistent so it's hard to give it straight praise, but the actors all seemingly delivered their lines consistently and the facial animation system is so astounding that their performances actually come through. This aspect needed to be nailed and they did it.
The story is a little mixed. This game is more like a series of episodes than a total appealing narrative. On the micro level, individual cases can frequently be engaging, mysterious and even well written. On the macro level, the main characters are often poorly mapped out and not given enough characterization to really get in line with. I know Cole has a family and a kid, but we almost never see them. Seems an important part of his life to be so overlooked. We know he went to war, but other than contextual commentary on how difficult it was to adapt to America after coming from the horrors of war, it never seemed particularly relevant to what Cole was doing. His war history didn't actually seem to change him as a person, in other words, so it didn't feel natural.
Now the gameplay itself is where the game tends to be the most controversial.
One, I liked the open world. I have no issue with this aspect whatsoever. It was hugely atmospheric, fun to traverse and filled with sights and sounds. Like Mafia II, it's not filled with boring little mini-games or sidequests. it is there specifically to heighten the experience of being a detective and actually performing your duties in the context of L.A. This is incredibly appealing as the apparent glamour and prosperity of L.A. directly contrasts with how the reality of the city is for most people, and I think it's important it was contextualized by this open world format. I'm honestly not even sure it's worth complaining about even if you DIDN'T like it, since you can just have your friend instantly drive you to whatever location you need to go to, thus effectively acting as if the game was a linear romp anyway.
Two, the driving is too loose for my liking. It's slippery around corners, the handling is often awkward for vehicles and so chases aren't as fun as they could be. That said, it's functional and I actually prefer it to the changes they made the vehicle controls in GTA4 compared to GTA3-San Andreas. But GTA3, VC and San Andreas have better vehicle controls than L.A. Noire easy.
Three, the shooting never gave me a problem. I've seen people say 'the shooting sucks', but this is inconsistent with my experience. The guns each have a healthy benefit or downside, I never had any problem with nailing my targets (auto aim off plz) and I was slipping in and out of cover with simplicity. I think a lot of the weapons are completely non-essential since the game takes a more realistic approach to how enemies go down (1-3 shots is all it ever takes), but I did like how if I tried to use my pistol to nail people from a roof Cole would try and miss 99.9% of the time saying (it's too far, I can't make it). But if I picked an appropriate distance weapon, all would be go.
Finally, I played the game in black and white and it really did capture that noir feeling. In this way, some of the visual issues seem to matter less. But it's not a completely attractive game... framerate can be iffy in a lot of the more intense action moments and outside of the facial animation, I'd term the rest of the game's visuals as "functional, but underwhelming." The audio however was consistently amazing throughout and is one of the best soundtracks of the year, hands down. The original stuff is just as incredible as the old classics, proving once again that whenever Rockstar helps out with anything, you can at least count on the music rocking.
So, yeah, I'd say... 7.5/10 if I had to go with a final score. Definitely liked it more than RDR.
