I like most of the info so far, tho the female SM sounds... icky.
I hope they don't have a mode specific achievements. I hate achievements that make you play on hardcoe or Legendary difficulty.
If it's stackable I don't mind so much but yeah, if you *have* to play 2 or more times just for getting the difficulty cheevos, that svcks. Even with a good game you would want to play again it makes it feel like an obligation/chore.
Not a fan of showing all dialogue options. What's the point in that? A way to show players what they're missing? The dialogue options available to the player should just be a reflection the player character's skills.
So you know what you might want to do with your next character that you didn't do this time. I agree though, it isn't ideal.
