There are a lot of people who are asking for non-human playable characters, but I'm not too fond of the idea, for a couple of reasons.
Firstly, a recurring theme in Mass Effect is humanity's role within the galactic society. Shepard is considered humanity's representative and more often than not his actions influence how the rest of the galaxy views the human race and also how humans perceive other races. I think it'd do a lot of good to keep this theme at the core of future mass effect entries.
Second, tailoring content to player choice AS WELL as race could (COULD) lower the overall quality of the content by putting too much burden on the development team. Mass Effect is an RPG that has its roots in player decision making and story development, something like DA on the other hand, while maintaining a healthy focus on the story and the world in true Bioware fashion, puts a bit more emphasis on the player's progression through the leveling system, increasing combat effectiveness and visual customization of the characters. I think having non-human playable races is a small step towards the DA formula. Like I've said before I think DA is a great franchise but it's qualities are not ones I would wish for the coming ME games.
Thoughts?
I agree.
I would add a few more reasons why playable species is a bad idea. It would be difficult and expensive to implement to any decent extent, and even then the payoff would almost certainly not be worth it. Just think back to exactly how much did different playable races mean in DAO and more recently in DAI. Those resources would be better used fleshing out a human character. Better CC, better animations, better backstory, better connection to the story, and so on. I don't like to pull the numbers game, but the truth is I don't believe aliens are actually in high enough demand from the general fandom to justify the opportunity cost.
Moreover, making aliens playable just cheapens them further. ME aliens are already far from alien and nowhere near as fleshed out as they would need to be to keep up with humans, story-wise. An anthropocentric perspective allows for much better storytelling from pretty much every angle. Plot, setting, and characters are better to introduce this way, and the themes are just ripe for the taking. Note that when I say anthropocentric I don't mean a "humans are the awesomest awesome awesome thing since awesome awesomesauce" but merely that the story should be told from a human perspective.
So yeah, I agree. It wouldn't be a big deal if aliens were playable, after all, but I would seriously prefer they weren't.
I have mixed feelings about having multiple playable races.
On the one hand having more options at character creation is cool, particularly if those options result in a slightly different experience while playing the game, and isn't solely cosmetic.
On the other...it does run the risk of lowering the overall quality of the game. DA:I for example was a less cinematic experience than the previous two games, with the camera positioned at a distance while conversing with many NPCs. That served to make the game somewhat less immersive than DA:O or DA2. While part of that was probably due the shift to a partially open world format, having to tailor cinematic conversations to multiple races at multiple heights and such would have been work compared to a protagonist from a single race. It does make me wonder if the multiple playable races in DA:I also played a role.
On that note...I suppose I'm in favor of multiple playable races if Bioware can produce a product that is no less cinematic or immersive than ME2 or ME3, and against it if they can't. While DA:I is a good game, I think it also had some very noticeable flaws. And I'd be disappointed if ME:Next was essentially the same game except in space.
Problem is, we can't have our cake and eat it too. Implementing playable species will necessarily mean sacrificing other aspects of the game, for an end product that is almost inevitably going to be half-assed.
