First, I have been playing Quest HD for about 2-3 weeks. AWESOME game. I haven't had a game pull me in and hold my attention like this for a long time. I love the "old school" turned based play, there are plenty of quests and plenty of options in character developments. I would recommend this game to anyone looking for a turned based RPG. (side note: I am a little disappointed to hear that the next expansion/evolution is going to in-game purchases. I find this tends to destroy the game play over time as the developers are looking for new ways to make fast money. However, I also understand that they aren't doing this for nothing. So thank you for your hard work.)
Finally, here is the point of my subject. I have found this forum to be full of great information. However it is a bit confusing filtering through the guides as they all appear to be for "the quest" I'm just now learning that not everything crosses over to HD from Classic. I have learned to look at the date of the post to help me know if it is for Classic, II, or HD.
SO, how much carries of from Classic to HD? i.e potions lists, how books are used, how skills expand, etc.
