The Remastered Edition essentially re-wrote the original games, keeping only the storyline and gameplay design but little if any of the original game code. Graphics, sound, and user interface were updated to modern standards, various bugs were fixed, and a unified authoritative gameplay was devised when it turned out that there were significant differences not only between parts I, II, and III of the original trilogy (such as the number of characters in the party or spells being available at different levels, or not available at all, in different installments), but also between ports of the same game. Some content was added, including female character portraits and (inconsequential) references to the Bard's Tale IV storyline.
