I agree that people that are new to DnD but want to experience Baldur's Gate, the combat system is going to be difficult for them. To me personally, I find it difficult to understand when a bad guy is in front of you and you use your best move and miss let alone a critical miss. To me that's seems crazy, no way should you miss unless the bad guy has some crazy ass armor or is a higher level than you. I know Baldur's Gate is DnD, but like you said, it's not going to attract new players that don't understand the system or if they feel like the game is too hard. Like Druid_NPC said, if they were to add difficulty setting like DOS has, it might be better for new players and for those that are having a hard time.
