What the title says.
As a long time fan of the Baldur's Gate series (long time fan meaning I started playing BG back in the 90s) I loved the nods to the original series with the book about Faldorn and then her being mentioned in conversation (I also loved the allmighty Booal, god of murder... ;P). Personally I'd like for the game to incorporate more of these, especially giving us details about pretty minor characters from the previous BG games. Stuff like finding "the broken axe of Korgan", meeting Coran in Baldur's Gate finding out about Shaar Tel's or Kivan's fate...
Pretty minor stuff perhaps but it would go a long way making old time fans of the series enjoy and accept this new chapeter showing it's all part of the same legacy without making that same legacy overbearing on the new game.
Thanks for your consideration!
