I played for about 3 hours maybe, maybe more. My impressions are that I haven't found a story yet. Sure we ought to help make settlements happen. That's nice and all but there is no plot as far as the trial is concerned. The characters seem okay so far. It seems the quippy Joss Whedon style dialogue only exists if you pick those dialogue options and apparently only for male Ryder. Which is good to know.
The musical score bores me to tears however. None of that cool 80s synth style tracks here. I miss that combat track that sounded close to ripping off the Blade Runner end theme. All we get here is boring orchestral movie sound track fair, and being exceptionally bland at that.
I will say however that other than the hair, which is clearly worse than ME3, the graphics are definitely improved. PBR was the right move, however they seemed to have stuck to plastic looking surfaces for a lot of the Nexus and Hyperion ship interiors, but once you see the tempest or recolor your outfit and armor you can really see that PBR work it's magic.
Particle effects are top tier, I was impressed with Inquisitions vibrant particles but these are vibrant and feel almost tangible.
Eyes still look a little funny because the iris is placed on the rounded surface. If you look at a real iris it is flat inside the clear rounded surface of an eyeball. As well the there is almost no texted work to be had here. The eyes look like a single solid color. But this is an issue almost every game has.
Facial animations are horrible, just really stiff. The face doesn't move enough. I just switch, within minutes of playing ME3 to this game and those facial animations felt a little better actually.
Now the important part, to me at least, combat. All the clunky awkwardness of the trilogy are gone. I haven't played with different weapons yet, but they feel about the same in terms of projectile impact. That is to say, there really isn't any.a tad disappointed with that.
The three powers thing I thought was going to be a huge problem... Until I realized in each game I really only had three powers I consistently used on each class.
In ME3 for example I used:
Vanguard: Charge, Nova and Pull
Adept: Throw, Pull and Stasis. Sometimes warp+cluster grenade detonations against armored targets
Sentinel: Overload, Warp and Throw
Engineer: Overload, Incinerate and Sabatoge
Soldier: Nothing, just guns.
Infiltrator: Tactical cloak. That's it.
I was concerned about biotics being neutered again, however this isn't a problem because biotics get bonus damage to shields this time around and can strip them to get their CC going. This is much better than reducing them to nothing but combos. I miss warp and it weakening armor though.
