Personaly i think that the majority of BG1+2 Fans could live with Turnbased if the rest would be kept in spirit. But sadly the game violates BG1+2 so hard in basicaly EVERY Area. The Change to TB is the most obvious at the first look. But if you are more opend minded and give it a try it becomes worse and worse..... from OVERDONE environmental ground hazzards, to Party size, to shallow character progression, to ridicoulus Jumping, to abundance of Health food (in combat even) so healers are totaly obsolete...... the list is almost ENDLESS.
In fact.... if they change the game to RTwP it would still not be a Baldurs Gate game. So the whole point is not making alot of sense.
