So to swing this more back towards DA:I, there's been a lot of talk on the forums about how the female companions tend to be human or elf and conventionally pretty, compared to the wider range of males. Do you guys find this to be the case?
I think this is definitely the case, although I would say the female companions are always more "normal looking" instead of necessarily pretty. They have less extremes than the male characters. You see this a lot in games with alien races, like KOTOR, SWTOR, and Mass Effect. Liara and Samara have very human faces and bodies, while Garrus, Wrex, Mordin, Grunt, Thane, and Javik all look animal-like and have some very non-human features. Tali is the only female companion that seems alien, but even then her face is hidden (so it COULD look human) and her body isn't that weird. This extends to the robot companions too, with Legion having a flashlight for a head while EDI gets a human face, hair, and sexy body.
You see the exact same thing in SWTOR too. M1-4X is a droid with a male voice and doesn't look human at all, while Scorpio is a droid with a female voice and is essentially the same as EDI. Also, all the alien female companions have human faces and bodies. The male ones are much more extreme, including Yuun (a fly-person), Bowdaar (a big hairy wookiee), Guss (a fish-person), Qyzen (a lizard-person), Skadge (a big fat houk), Broonmark (a big hairy talz), Khem Val (a big scary monster), and Xalek (has a bone face).
Dragon Age is a bit trickier since all the races are very human-like, but I would consider qunari and dwarves (if only because of body size differences) the more extreme ones. So Shale and Sigrun compared to Oghren in Origins, Oghren in Awakening, Sten, Varric in DA2, Varric in Inquisition, and Iron Bull. So yeah, the Dragon Age games aren't quite as guilty of this as some other BioWare games but I would like to see more non-human/elf female companions. Hopefully we'll see some in the future.
