I was plagued with the infinite loading problem, and I also had random freezes in the middle of the fight, so I didn't get very far in experimenting with the game.
I got very familiar with Ctrl+Shift+Esc and force closing the exe.
From what I got to experience, the little snippet of the story I got to see was interesting. I'm keen on finding out more about the universe, but knowing BioWare they shouldn't disappoint too much.
As for the gameplay, as sum1 said, I'm probably spoiled by Destiny2 and feel unsatisfied with the gunplay. They don't feel powerful enough, and the synergy isn't really there. I don't feel like I'm doing much and I seem to be dying a lot initially because of that. Maybe with stronger weapons that you unlock later on, it may change, but from the few I've seen, Assault rifle is alright, SMG is pretty awesome up close, the marksman rifle is weak... unless I can 2 tap heads, but it's not as easily done vs in Destiny2. Didn't get to try the pistols or Sniper Rifles. Was going to, but the game got stuck on loading again and I just gave up.
The movement felt bad initially, but once I got used to it, it became much better... again, probably spoiled by Destiny2.
The first mission was alright, albeit being super confused in the "vault"? with the 3 colored portals and the shield bubble thinggy. We (our group of 4 randoms) were just lost on what to do. Was there a pattern we missed? an indication of what color/shape we should choose on which portal? until I just tried to melee the shield, and that seemed to work?! There's no indication anywhere as what to do... I don't want hand-holding throughout the entire thing, but at least give us an idea of what we should be doing?
I'll wait for reviews on release and see if I want to play it further or not.
Been burned by EA too much.
Customization seems quite vast. I haven't unlocked the other Javelins so I only played with the Ranger, but I've seen other players in Colossus and Storm, and they do play quite differently. I probably will spend 2 hours fine tuning the first Javelin, and then just put everything black and yellow in the others like I do with other games.
For now, I got Ace Combat 7 that I'm going to be spending most of my time on...
