The romance options, Isabella and Merrill, were clearly designed with straight male gamers in mind. Unfortunately, these choices are what one would call “exotic” choices.
So I guess Bioware aren’t ignoring all straight male gamers, just straight male gamers who want to romance mundane female characters. Seriously, though, Isabela? Exotic? Sure, if you met a foxy dagger-wielding pirate captain down the pub that would at least warrant a raised eyebrow, but in Denerim or Kirkwall you can bump into six more exotic things before breakfast.
Fair enough about Merrill, though, she is a strange, mystical creature from a far-off land where they have peculiar customs. Still, that’s the Welsh for you.
