BG2 original (aka "Baldur's gate 2 complete") is included as part of BG2 enhanced edition on GOG, check the description :) I too prefer the original versions, particularly because there's a mod called Baldur's gate trilogy that combines both games and their expansions into one huge game with a ton of fixes.
