I am just another player who has enjoyed and cursed the game at times. Probably I spent less time with TW than most here and my opinion is utterly unimportant. Kindly consider that I am not an expert (of games as a whole and this special one neither) by any means and that my assertions are only based on my limited experience with the first game alone. I certainly did not explore any shade of the game and you are very welcome to impart your knowledge, your own experiences and your own opinion with me; I assure you that may point of view is not set in stone.Both games do just this, to a degree rarely found in RPGs. I'm not sure why you keep asserting the opposite.
That being said, it was just my impression that Geralt's choices in TW1 not had the impact I expected. I know that there were differences, but eventually they did not matter too much. Choosing elves vs. the order, medic vs. sorceress, heal/cure the guardsman (Vince?) and Adda - I felt it did not change much in this world and for Geralt. Even your entire role playing attitude would not modify the end of the game - no matter if playing a warmongering, violent badass or a "true" witcher using the sword only as his last resort to solve conflicts. Finally you slaughter Alvin and he did not even spit one single word referring to your efforts and your shared past regardless how much you cared for him. However, this was explicitly my (non-power-gaming) impression and in fact I could have missed something.
Now that's interesting! I happen to read ASoIaF just now and so far (currently 3rd book - a storm of swords) enjoy the story. You are right, in quite some aspects this universe bears a almost striking resemblance to the world of TW. Did not think about it until you pointed this out, thank you very much.The story is great, multi-layered, and laden with psychology. Sometimes a single phrase makes three statements at once, and directs the events. I actually even doubt that some of it was intentional because of how good it is. But in order to grasp it all people need to play the game at least twice, with two different ending each, and not everyone will be OK with some of the consequences. Well, if you truly like ASoIaF, and do not mind all the death and brutality, TW2 is for you. In this case I am sure you'll eventually be able to find the most enjoyable way through its story, with the most agreable outcome. But player'sdiscretion is definitely advised.
Looks like I have to get a new graphics card, thank you, too. I think I'll give it a try then.As it has been said, the choices and consequences are more pronounced in TW2 and have a deeper impact as well. Heck a decision you make in chapter 1 completely changes the 2nd chapter's story, the npcs you mainly interact with and locations you visit. It really is a game you really need to play more than once to get the full experience by the way. Is that what you were trying to ask?
