New Protagonist in MEA2

Given how I spoke against this, I am honestly surprised to say that I would like for them to continue with Ryder as the protagonist.

I like Ryder as a character, the squad as well and feel the set-up of Ryder as a Pathfinder would allow for an easy way of continuing the story since, well, exploration in a new galaxy continues. Weave the new story around that and we're go.  Still a lot of different paths a story can develop from that start. The background could continue to be colonization, building a galactic civilisation, keeping peace between the different people and sorting troubles while exploring the unknown and making first contact with new races.  

If they wanted to, they could even introduce new characters for squadmates by rotating the crew members. Personal or business affairs requires them to be elsewhere so some squadmates may be away for a portion or the entirety of one game and be rotated back in the next game with other squadmates then temporarily leaving or staying. To compensate for this, they could have a focus role in the DLC of the game they have a reduced role in. New squadmates are introduced but content isn't stretched thin and the squadmates rotated out still gets time of their own through dlc.

I think this could work rather nicely as long as they're careful about not falling in the old traps of creating a worldstate that becomes difficult to maneuver. Stay away from too grand decisions and too diverging paths. Stick to personal choices and that sort.

Keep this Dragon Age shizzle away.

Considering BioWare has always taken the approach of letting you customize your character including gender, I don't see them forcing you to play as the sibling you didn't pick in Andromeda.

I do like that Dragon Age can go into each game with more of a clean slate than Mass Effect did with the trilogy. Choices carrying over is nice and all, but when you have this many choices the vast majority of them just aren't going to matter or are going to start causing issues down the line when they have to account for way too many possibilities.

I think they are keeping options open depending on how is Ryder received. If well, you will play as him/her in the sequel, if not, a new hero.
Tbh, I really love Ryder and would love to continue playing as this character. But I am worried we will have a new char since the game has a mixed receptions rn.

One of the best things of ME is that the characters carry over. It seemed that they approached each sequel as it came and so the carry over of the squad wasn't always implemented in the best way, but it was still awesome to see Shepard through more adventures with familiar faces and watch relationships grow over time. You miss out on this with the DA approach. Plus, so many heroes and their company occupying Thedas is getting a little ridiculous.

For Andromeda, looks like they have it set up to bring these characters back in better ways for the sequel since they got some experience under their belts. Continuation of squadmates and those that decide to leave, more meaningful appearances than a few minutes here or there of nine different squaddies. Ryder is also growing into the role of hero. I want to see her through.

Based on the criticism I've been reading the last few days regarding the writing and voice acting I think a lot of people would prefer Scott Ryder to be the Antagonist in MEA2

That's on Bioware if they do that; it will be just like when they just flat out removed the Mako from ME2 just because a lot of people (rightfully so) pointed out that the Mako sections handled very poorly. Hopefully, even with any criticisms the Ryder twins or any other part of the game may be getting, Bioware will take those criticisms and use them to improve the game and not just completely remove everything that people had an issue with.

The "Dragon Age approach" only exists because pathetic fanboys and fangirls hated on Hawke so much.

they said it's not a trilogy, but still we ca have the same protagonist: Ryder, again we choose shich one, i'd like that
ME is about the story, so the same protagonist could involve the player a lot more than having new protagonists

With the amount of hilarious gifs and memes associated with the Ryder's, I dont see how you bring them back, unless you give them entirely new faces. Maybe some DLC where they are horribly disfigured and undergo a head transplant (which ironically is happening in real life lol).
