Things that don't make much sense. (Tiny Spoilers)

No, Sara accompanied archaeologist teams in a support role for the excavation sites. She wasn't an archaeologist herself. 

It's lines like "The first time I handled a prothean artifact, I was hooked." that made me think otherwise.

Well, the purge wave that came out of the Remnant tower did fling them off of the platform, and when Ryder was clinging to the edge, was hit by some debris that was being shot off of it. Alec was injured as well since you can see him limping.

That just made me realize that the second time the jump jets were working, so they could have used them to break their fall, but both Ryder and her Dad ran out of jump jet fuel at exactly the same time.

Maybe, we don't really know the specifics of Ryders medical condition and when the problems of SAM-implant overload began. An arterial blood gas would shed some light but as usual in media they don't go into specifics about the injuries. I guess they could have Alec scan Ryder and then  have SAM spout som jargong followed by the same scene we already have but I'm not sure how that would improve the story.

Or they got some (seeds) from the Quarian fleet garden ships.

Yeah, Daddy sacrifice has no sense at all. At the beginning Ryder was able to fix his broken helmet in 2 seconds with omni-tool, but later after the fall suddenly he couldn't ? Alec too ?
Odd, very odd.

The entire front of the helmet being shattered is probably a bit different then it being cracked.

Did they run out of fuel?  I don't recall that being said.  I just thought the force of the wind(?) was so strong that it overrode any ability of the jump jet to break their fall.

Why are there land vehicles parked everywhere yet no one every drives them.

Why have mechs as a mini boss yet never have them respawn in the open worlds

Why is the same wildlife in every planet? Who thought yup, this seems enough. Missed opportunity for sand snakes, space buffalo, xenomorphs, spiders, etc

Why is there no funeral for Alec ryder?

why doesn't peebee and Jaal have an alternate outfit with an enclosed space suit?

Who decide Ryder's jacket outfit looked good in comparison to Sara's or Shepard's

I'll have more later

It would have been interesting to come across moving vehicles. From the looks of them, they're unarmed transports, so they'd be pretty easy targets for us if they were objects we could interact with. It would have been awesome to be able to ambush a kett supply convoy and ransack their stuff. But then, we should be able to shoot shuttles out of the sky as well. 

I'm kind of glad mechs don't respawn in the open areas much. If anything, I think that the mechs should be tougher with more abilities (like cluster grenade launching and greater mobility or something) to greater justify their being more of an "event" boss. 

I have a similar gripe. My thought was that perhaps the cluster's being largely engineered by the Jaardan to have life may account for it, but the varying environments make that questionable. Like, each world should at least have some fauna specifically adapted for the specific environments, even if they're fauna we can't interact with, like say on Havaarl, there's some arboreal life moving around in the trees, like simian-like creatures or something like that, and smaller desert creatures on Elaaden or Eos that quickly disappear into the sand when approached. 

You know, I never thought about the funeral. That should have at least been a post-campaign thing. But really, forget about the funeral. Where is the body? Surely they took him off of Habitat 7's surface. 

The lack of sealed armor thing is basically why I treat Jaal and Peebee similarly to a lot of ME2's crew, which I hate. I strongly dislike having to select a squad based on who can actually look better equipped for a certain environment. It would have been no thing to just have Peebee wear basic Ai armor and Jaal to wear the fully sealed suits that the Angarans already have models available for. This is why I think that "iconic" looks are a crock of shit that BioWare should really get away from.

Yeah, Scott's jacket sucks. The reversal is funny. Shepard's jacket was better than any casual wear FemShep had, now the other way around. 

There's a few things I can point out, but the big one for me is the master stroke sequence of the game.

The faceplate was completely destroyed in the second mishap. Who can say that the omnitool would have sufficient minifacturing materials on-hand for such a serious repair, after already doing an earlier repair?

Also, unwanted , Alec didn't repair the monolith on Habitat 7; he shut it down and ended the machinery+Scourge energy loop. The terraforming machinery is too badly damaged to be deactivated on Habitat 7.

EDIT: Perusing the thread, I'm seeing a lot of misunderstandings and false arguments that could be fixed by paying better attention to the game. Maybe I'll revisit some of them when I'm not stuck browsing on my phone.
