I've been playing it all day today. It's not horrible. The best way I can describe it is 'generic'.
We're in an alien galaxy that doesn't feel all that alien. The remnant technology and sites feels just like the Prothean remnant technology and sites. Cold metal corridors that don't really differentiate themselves.
The Nexus is just Citadel 2.0, which I can kind of forgive since it's from the milky way, but man did running around the place get old quickly.
The Keht are the typical silent evil species that captures, tortures, and kills every other species. Basically Collectors 2.0. Not a fan of how similar they are to Milky Way species either. Bioware should have been more imaginative with the new species. Especially considering the fact that they only introduced 2 new species along with some boring typical robotic enemies.
The quests have also been pretty typical. It's basically all "go here and press Y/triangle to interact with something" mixed up with some shooting. The shooting is damn good though, at least.
On one hand, it's nice to have every ability open to me, but I feel like it will take away from future playthroughs since Ryder can have all the best biotic/tech/combat upgrades whenever he likes. They should have kept the specializations from previous games. This would have done wonders for replayability and made it feel like I was truly customizing my Ryder.
The soundtrack has been passable to non-existant. Some ambient music while exploring would have helped the atmosphere.
The shipmates don't really stand out so far either.
Hardcore Krogan than likes to kill shit? check
Attractive (better than the competition anyway) badass soldier chick who serves as a generic love interest? check
Genius full of himself Salarian? check
A bunch of boring humans we'll never care for in current or future installments?
Weird hyper quirky "lovable" autist? check check
Not all of it is bad though.
Vetra is the only one whos grown on me. She's got a good head on her shoulders. I like her focus, humility, and down-to-earth-ness. She actually comes off as unique. She's still no Garrus, but she would have fit in well among ME1-3 shipmates.
I like how you shape the Nexus/how that manifests as perks and progression of the initiative in that you pick outposts. The idea of exploring the galaxy, and teraforming suitable planets to fit the different species is pretty cool too.
The best part though, is Male Ryder. I played him because a bunch of reviews specifically noted his stand out voice acting. They weren't kidding. His animation also doesn't ever look awkward. Male Ryder is the way to go for sure. It's just a shame about the shitty character creator. It basically forced me to pick default Ryder.
