First thoughts:
The Good: The story is outstanding, the voice acting is S-Tier, and the graphics are beautiful. I guess not being a free movement intensive game they can cut corners on what has to be processed, because even on regular PS4 it looks like a high end PC max settings game. Just playing half way through this so far, I'm already sold for future Quantic Dream games. The end of each mission has a flow chart that shows you everyone's choices compared to yours, and even a narrower friends choices which I find to be most interesting. I believe Strider and one other person are the only people that have played on my friends list. I've seemed to line up with them for the most part until recently when I realized being "good" or "understanding" doesn't always help you with the karma system the game has... it's very shades of grey, so it better not to stress to much in being nice or trying to cater to NPCs.
The Bad: The controls are pretty wonky. Unless its a certain mission segment, and very few of them, there is no free roam camera. Its purely PS1 Resident Evil style camera that is slightly more modern. There is a way to free roam, but its slow and not optimal. The investigation button allows you to pan the camera for clues, but time is frozen while you do it. Outside of that you can flip the camera with R1 and it generally doesn't do a good job. Often it will flip into some useless angle, and hitting it again will most of the time never send you back to the view you just had. This is irritating when there is a viewable item/area you walk pass. You'll have to go into the investigate button to pan to it as these often pop only when you're super close. This is pretty much the only negative I have about this game. The style presented makes it forgivable, but it would have been nice to have a more free flowing camera system.
Thing to know: This is no Telltale game. If you fuck up, there is no going back. The show goes on leaving you wondering what could have been. This def adds to the replay factor if you have that kind of time. Decisions are forced up on you to decide uncomfortably quickly. While it sucks at times, it really adds to the emotion it provokes out of you. I have several regrets already. I selected casual controls for this go around because it made it clear in the opening menu, if a character dies, the story doesn't stop. I didn't really want to miss out on 3rd of the flow chart.
