I've replayed dragon age and mass effect recently, while being on both subreddits. Mass Effect's lack of materialism makes the game worse, and its community worse.
Please read
I enjoy both but its really cemented why I love dragon age so much more.
These are story based games set in worlds created entirely for these games. Its common to have discussion about how different story events could have gone differently, or what will happen in universe after the events of the most recent installment. Obviously, how these worlds are set up and how the story is told effects the discussions a lot.
In mass effect society spreads across the galaxy and encompasses trillions of individuals across thousands of planets. Despite that, the major story beats hinge on how you treated individual characters, or whether they are alive or not. Like whether an artificial plague causing 99% of krogan pregnancies to miscarry is justified is completely down to whether the good leader is in charge.
Despite trillions of individuals and complex economics all major conflict boils down to species versus species. All krogan, all asari, all turians are just like that so of course this has happened. There are hints in game that there are many different cultures within each species but we get very little evidence of that, and almost entirely in the 3rd game. Krogan (giant toad people with natural armor, anger issues, and a love of violence) are shown to be maybe not inherently violent individuals that care a bit about others, but thats mostly it. We get one pretty butch Asari (otherwise all feminine species).
So when the community talks about these things its always on individualist or species based terms. It is almost impossible to do materialist analysis because of how the games are made. When the community talks about the game arguments are more heated and personal. There are lots more gotcha type lines than in the dragon age community. I suspect this hostile dynamic could contribute to why there are obviously way more women and queer people in the dragon age community.
Mass effect's story is also about exceptional individuals overcoming impossible odds, which lands way better with men, in general, than women, in general.
In the dragon age community discussions revolve around things like, how does the church use drugs to control their private army? How will giving the dwarves a tool that enables them to put their souls into tanks effect their society? How do independent kingdoms respond to a paramilitary organization run by a prophet encroaching on their land?
Mass effect discussions are, "do the volus deserve a council seat?" Instead of, "How could the Volus get a council seat?" or, "How will the volus having a council seat change existing power dynamics?"
Dragon age stories are, "how does magical talent being both random and dangerous effect society?" "Is it worth it to consort with demons to gain power?" Mass effect stories are, "oo ouch owie my magic gives me migraines." (I like Kaiden don't @ me, the whole child soldier bit both games have is nice)
There are other differences too, like dragon age having braver character writing that scares away some of the chuds. Most people on the dragon age subreddit don't like Vivienne, but understand how her inclusion makes the game better. That kind of subelty doesn't exist in mass effect discussions because the game literally wasn't designed for that level of depth. All characters that are apart of your "squad" are meant to be likeable or at least the kind of person their players would respect. Dragon age release characters also in your "squad" like Sera and Vivienne knowing that tons of their players will hate them.
In summary, mass effect is lacking a pair, let alone a quad. (krogan have 4 testicles) (Please laugh I mentioned testicles)
This is underselling ME3 a bit, it was relatively anti-gamer for its time. ME1 and 2 get the tho. Even though I like them anyway.
Edit: how could I forget Dragon age has literally actually good trans representation. Theres a FtM guy whos literally just the coolest fighty bro and his dudes respect him.
"So If I grew up under the Qun they'd treat me like a real man?" "You ARE a real man Krem."
Edit 2: adding data from reddit surveys
The dragon age subreddit is 45.2% women (3.2% trans), 44% men (1.9% trans), 9.1% non binary and 1.7% other. 45.3% Heterosexual
The Mass effect subreddit is 76.4% men (0.6% trans), 19.7% women (1.5% trans), and 6% total trans people. 73.9% hetero
You're telling me that the game series where you become a member of the spectres which is basically the Space CIA who have the ability to act with total impunity under the law and is portrayed purely positively might have some problematic elements?
Really, though, I wouldn't have a problem with the existence of spectres if there were more people in the games going "hey don't you think that this whole organization that can do whatever it wants without accountability is kinda messed up?" Like they don't explore the concept at all really it's just an excuse to give Shepard, and by extension, the player, more agency.
