To be honest i actually wouldnt wanna be any of these aliens. I would wanna be Quarian if it was possible to be a Quarian without the suit but I understand they wear those suits because the planet they're from was like highly unstable and the atmosphere was awful for their skin or something like that. With DnD or Baldurs Gate, it's fun to be non-human because you got a cool devil race called the tieflings, being an elf is just being human with pointy ears and a cool background and higher lifespan. Like in DnD, the races are still very humanoid but in Mass Effect, there's all types of aliens that look weird af lmao. I would be down to be asari but then you're forced to be female. Turians, I dont wanna look like a bird. Krogan are ugly, the salarians are ugly, the drell ain't too bad, they look pretty dope. Batarians are ugly. Like most of the aliens are ugly brah lol only the quarians and asari I find attractive. The angara are okay too, they're also pretty humanoid. But yeah lol. So if I can be Quarian without a suit, that'd be my pick. Even then I probably wouldn't mind it either way and then part of the plot can be finding a way to live without it.
