Just to round this topic out:
1) HiG aren't making anyone buy the new edition.
2) If changing the art, encourages people, or a broader range of people, to play the game, then great.
3) The designer did state that their original plan was to have a range of people represented, but this was accidentally lost during the design process.
4) I agree that our games should, and do, represent us.
Drodo won't be able to reply for a few days after their last post.
But I won't be deleting posts, I'm happy for the world to see people's opinions.
