IMO you nailed it. It's not a bad game per se, especially after they fixed some things, but it's no where near the quality of the original ME trilogy.

I don't know if you consider this a spoiler or not, so maybe stop reading here if you're concerned about that... But the thing that bothered me the most was the lack of alien diversity. They went to a whole other GALAXY and both of the new sentient alien species they encounter are bipedal carbon-based lifeforms. To add to the disappointment every race that came to Andromeda is also bipedal and mostly carbon based, so it's actively less alien than the original games even though we're in a whole new galaxy. No hanar. No Volus. No elcor.

And every Asari face is literally the same model except for the crew member you have with you. They all have literally the same face. Idk. It really bothered me.

Another thing that's annoying is you have less control over your squad mates in combat. I really enjoyed the way combat sometimes felt like a puzzle in the OT, bringing certain people for certain enemies and combining powers so each of you are stronger together. It felt like teamwork even though it's really all you. In Andromeda they basically just made the main character OP instead and that's the only one you control.

With that said, it's still fun! And I think it's worth a playthrough or even two. Just don't expect it to be Mass Effect.
