Long post incoming! I feel like i'm playing a different game to most people here, as I'm having a ton of fun. However, I'm also not having the performance issues that are plaguing a lot of people so that no doubt helps a lot. I'm playing on a i7-7700k, 16gb ram, 6gb 1060 Strix and it looks good and runs well, bugs aside. Also using a controller since I've heard so much bad stuff about the KB/M controls, though I'll try using the updated KB/M at launch. Mostly playing Ranger with a smattering of the Storm. Didn't gel with the Colossus at all and haven't found the right build for Interceptor yet.
Pros:
Combat feels amazing, with the manoeuvrability of flying, hovering and the dash i'm zipping around everywhere constantly. Using abilities as much as possible and shooting only when they're on CD. Staying on the ground and playing it like a traditional third-person shooter is Doing It Wrong, and I suspect a lot of the posts of "I played it for 10 minutes and it's boring" are from people who are Doing It Wrong. This is subjective of course, but I really think the 'loot-shooter' label is giving people the wrong idea. The shooting are the auto-attack canapes, the abilities are the main course of combat.
All the javelins feel and play very different and with the various gear options I can see there'll be a ton of viable different ways to play at higher level. First GaaS where I actually feel like the classes are more than just minor differences. I'm really excited to see how the masterworks will allow some crazy powers.
Love that everything has matchmaking and I won't be locked out of any content because my friend's aren't interested in the game.
Customisation is amazing, with huge variety of options, and that's with barely any different armours available to experiment with. Can't wait to play Dranthem. Really like that cosmetics are separate from gear so you don't have to look like a mutant of different styles because it's the most powerful combination, though I understand some people dislike their power not being represented visually.
Cons:
While it's more stable than last week with a lot less infinite loading screens, I'm still occasionally being kicked back to the start screen or unable to finish the stronghold because something is bugging out with the objectives or a door isn't opening. This better be fixed for launch or this game will not be received well at all.
Loading screens. Like lots of people have said, there's an abundance of loading screens in transitioning areas and it's tedious. I really hope this is reduced for launch.
The menu system is one of the worst I've ever used. Holy shit, it's so bad. Completely unintuitive and with loads of unnecessary steps. Just no Bioware, baby wot is u doin? Again, I really hope this is a placeholder version and it's improved for launch.
Other thoughts:
Sound. All sounds good to me, including weapons. The number of complaints about it is making me wonder if there's audio bugs I'm not getting? having said that, I've twice got the all audio being silenced bug that seems to happen to a lot of Frostbite games. Have to quit out and restart the whole game, and it's irritating as shit if it happens mid-stronghold. it was unbearable in Andromeda, better be fixed asap.
I think a lot of the complaints about the game being unbalanced are pretty hasty. We're playing a small slice of early game and I'd hope the balancing is around end game, not levelling.
The lack of tutorial is reallllly hurting the demo, as it throws us in the deep end with this obtuse UI and no attempt to explain the right way to play - see my earlier point about people Doing It Wrong.
Story, dialogue. Eh, hard to say from this small slice. Story has a bit of intrigue to it but again we're thrown in without context so it's hard to care. Dialogue is fine, usual video game nonsense. I'm a bit befuddled at a lot of the complaints about it - the number of games with actually good dialogue I can count on the fingers of one hand. What exactly are people expecting, Citizen Kane?
End game concerns. Impossible to say really without knowing what's in at launch, what the road map is, and speed of updates. Only three strongholds is definitely an eyebrow raiser but I'm reserving judgement until release. Though having said that, I think people have weird expectations about the amount of end game necessary. There are loads of games where you pay your $60 or local equivalent, play for 20-30 hours and bam, done forever. If you play this game for 100 hours and run out of endgame content then you're still definitely getting your money's worth, and that's not even counting whatever updates they have. There's no sub and all non-cosmetic DLC will be free (except possibly more javelins which is TBD) so it's not like you're continually paying more for the privilege of not enough endgame.
AI. Definitely a bit poor. I know it's a Diablo quantity over quality situation but still, bit dumb. I seem to recall hearing that the developers had found a bug in the AI in this build that they've fixed for launch but I can't remember where I heard that so can't verify.
Freeplay being disappointingly closed off. This I think is because lots of it is blocked off in the demo and doesn't reflect at all on how it's going to be in the full game. Being kicked back to loading screen with only 5 seconds grace time to turn around is irritating as shit though, what were they thinking having it work like this for the demo?
Fort Tarsis. While I agree that it's a bit lifeless at the moment, this will likely not be the case at release. You can't go places or talk to people that you will be able to in the full game, and the devs made a big deal on one of their videos or streams about how Tarsis changes and upgrades as you play the story. You can tell that it's a decaying backwater in the demo stage of the game, and I fully expect it be a more, bustling, dynamic place once the campaign is finished.
