I love this game, after playing it, no other game picks my interest, except Dead Space 2
but that is another genre altogheter. The only things i really regret is:
a) Too less choices that has really tangible consequences. I recall the arian la valette cutscenes, there are at least 3 for each different decision, but in all the game, more of the cut scenes are for the memories of Geralt, so i think in that area i feel the witcher 1 was more about choices, also the 16 endings it is kind of an exxageration and a good use of words, because more than 16 endings there are 8 kind of choices across the game, and their binary consecuences.
In witcher 1 even the small side quests sometimes had cutscenes, and the major ones were outstanding. I coudnt sleep after i knew what happened to that she elf leader after i sided with the knights. Here in witcher 2 , i see a amazing story, but sometimes the story carries me, not my choices.
The game is too short. Prologue, chapter 1 are 2 are ok in lenght, but chapter 3 seems as an epilogue in itself, and the epilogue is far more shorter than the one in the witcher 1. Dont get me wrong, i love the game, just it seems that this areas are lacking.
Apart from that, the game is the most awesome thing i ever played, only surpassed by The witcher 3
Hope they release some dlc or expansion soon, the ending seems more like a beggining for me, it left me with so much need for more.
