Besides my previous post in this thread and most of what's been posted by others and I fully agree, there some more I can share and even more that will go unsaid, which keeps me playing this game.
- The Battle of Kaer Morhen - It's so epic that it gets me yearning for it. Even if goes so fast now that I rarely even get damaged in Death March (experience is the most valuable weapon in any game, IMHO). It has the same feeling as The Battle of the Crossroads Keep that made Neverwinter Nights 2 an awesome game. (and in some proportion, the Siege of Gondor in TLotR:RotK)
- Johnny - One of the best characters created, in my opinion. I just love to hear him talking, after he can talk of course. Clever, wise, jolly and pure. And one of the most intelligent beings I've seen in any game. It's a pleasure to interact with such a being.
- And as I started playing with Music off (after some 1200hrs it becomes enervating really. I like TW1 and TW2 soundtracks better), except for some very special cutscenes, I find the atmosphere of the game so thrilling and captivating. One of the best sound effects ever, movie or otherwise, which makes me feel deep inside that very world as a real part of it.
