The 30fps cutscenes are jarring and make my skin crawl, but at least that's a demo-only hitch.
The shaky cam during cutscenes and dialogue is bizarre, nonsensical, and awful; it actually makes me want to look away from the screen completely during dialogue. Dear god, I hope it's at least a toggle in the full game!
The prologue itself is almost laughably boring. Inexplicably boring. It's the section that should come after the exciting introductory prologue. Long stretches without any player input and world-building at the expense of interaction. And it's long itself It's difficult to comprehend what they were going for here. Story itself is I guess serviceable, adequate for the genre. It's at least there, which is something. Could get good but not expecting much.
All that said performance in the actual game is really good (on PC at 1080p/Ultra with a GTX1080, will try 4k/Ultra later on my other rig), the foundational systems seem pretty well thought-out, there are early signs that they built a good loot system which is a huge part of this, and it's a ton of fun once you get to start messing with your class and feeling the potential. Sucks that you have to slog through to that point. People are going to be telling newbies to "just get past it" about the early game left and right. It's a great touch at least that you can skip the prologue on characters after your first. Controls feel good, a lot like Gears, at least on PC with a gamepad.
For anyone who may be struggling with the cover system, playing via cover to actually tackle combat encounters (a la Gears of War) is not intended and you seem to be really punished for trying it. You can use cover tactically (Technomancer for sure can really take advantage of this) but taking cover while you're under fire is not the way to go and you have to shed that instinct. Aggression is the name of the game here, almost Doom-style, and understanding your class' healing gimmick is crucial for survival rather than staying in safety. There was a message from the devs about it on login, but the tutorial obviously doesn't convey this at all, so yeah.
