Should bioware do one final shepard game?

Debatable, considering the nagging sequel bait it tosses into a post-credit scene, suggesting that the Kett may not be quite done. That and the fact that Ryder is still very much alive with few wide-sweeping world states to account for at least leave room for more manageable continuity. 

Don't need Ryder for that.

Ryder being alive doesn't mean anything. Look at Shepard. He/she dies at the beginning of ME2, and because of plot, he/she is brought back from the dead.

With regards to world states, yes it's more manageable to continue in Andromeda. That doesn't mean a continuation can't happen in the Milky Way after the events of ME3. If a sequel is to have Ryder return, would all the pathfinders return as well? I ask this because the turian and asari ship missions are optional. Would Bioware bring in a 3rd va for the asari pathfinder? If not, is Bioware going to have it where that ship was able to get to the Nexus? How about the turian pathfinder? I know both need to be completed for Dunn to survive.

Bioware would have Dunn step down, regardless, in the sequel and might get a small cameo, present another fodder character who may or may not die and either be killed off screen between Andromeda 2 and 3, or be killed off in Andromeda 3, because "real" consequences. I am not invested, because even if he survives the entire way through, his involvement will be minimal, as will be every character with a potential lethal path. At this point, it's just detrimental to my investment in the franchise and my belief in Bioware to make significant commitment to the player's choices being realized in any meaningful way.

Sorry, my bad. As I've said before, I don't think of these characters, I hardly remember who they are and I often mix them up in the game.  I don't even know/remember who dies. But, either way, I expect Dunn's fate to line up with the above, regardless.

Indeed. Hopefully Naughty Dog can get in touch with the Mass Effect Andromeda writers, and really try and pin down some of the genius that went into incredible lines like 'my face is tired'. 

Actually, not just the writers. Naughty Dog need to get in touch with MEA's designers as well. As I was walking through the painstakingly detailed cities of TLOU2 I was thinking to myself "Man this is ok, but I really miss driving around Voeld and freeing 0/8 hostages".

Like I said, it’s not a matter of necessity. What I am saying though is that Ryder at least has unfinished business that could just as well be attended to along with the continuation of the setting. There’s no particularly strong reason not to follow that thread with an established character with ties to that narrative, other than “I don’t want it”, of course.

I’m not sure how that’s really a rebuttal. Sure I want Ryder to return, that much is obvious, but I don’t think the situation you speak of is the same as the one I’m referring to. The situation is simply that Ryder is narratively the most qualified character to continue any threads following the events of the first game. If you want to fabricate a new character to follow future threads, that’s fine, but this phantom character and companion roster has no history or connection to the story that we’ve observed so far. 

It’s not a matter of whether or not something works for me, but the writers making a world state function by making the appropriate story decisions, either by canonizing a specific world state scripted by Mass Effect 3, or cherry-picking elements in a combination they feel might appeal to players the most (e.g., picking Destroy, but the geth and EDI get to live). 

It’s not likely that BioWare would ever have the reapers play an active role in a future game again. The trilogy exhausted them, and there’s not much value left in them other than just remembering the history of the previous games, like perhaps seeing a reaper husk half-buried on Tuchanka or something as remnants of a long-won war. Frankly, trying to do more again with them would be extremely disappointing and show that they’ve finally run the well completely dry. There’s so much presumably unknown throughout the galaxy. It’d be a shame to squander it on something we’ve already seen enough of for years. 

”Reapers? Ah shit, here we go again.” 

I'm noticing a trend of people calling things 'bad writing' for things they just don't like. 

I feel like I'm quite measured in my criticism honestly. In particular, I've probably praised MEA and DAI as much as I've criticised them. I just don't want useless bullshit in my games. 

And hey 'my face is tired' is a damn good line. 

Unless they’re referring to things that they don’t like because characters have to essentially betray themselves via the idiot ball to get dramatic moments rolling.  

Why are assuming I would want the reapers to have an active role? Is it because I mentioned they could be involved in any capacity? The closest I would want the reapers to have any role would be through dialogue and flashbacks.
