Enjoyed this game quite a bit. Finished one path (Roche's) and will reload to to the other (Iorveth’s), as that decision offers the biggest change by far, altering half of the game's missions.
The first game was a real diamond in the rough–a noticeably limited budget held back some aspects of the game, which were partially fixed in the enhanced edition. The story and varied gameplay was the glue that held the unweildy beast together
The story here follows up nicely from the first, the only main difference being that there is no neutral path and that Geralt is more unavoidably mired in the politics and plots within the game. I am very pleased to see a true branching storyline, which I haven't seen in a game for a while, sadly. Both branches use the same maps, but the conservatism here is nowhere nearly as noticeable as DA2. Only a few characters show up from the first game--Zoltan the dwarf, Dandelion the bard, the girlfriend sorceress Triss, and the king of Temaria. Geralt's backstory is fleshed out further in this game (in some very nicely done flash animated scenes) and, in a nutshell, is essentially on a manhunt while doing his best to get through a very fractured social and political atmosphere. There is also a bit more focus on locating a person of Geralt's past connected to the mysterious Wild Hunt of the previous game.
The game is more cinematic and "linear" this time around, but certainly for the better. Outside of the Prologue, there are three principal areas in the game, and each gives an ample amount of sidequesting and rummaging around for items. There is none of that MMORPG-style "collect 10 basilisk skulls" type quests, thankfully, but a few monster-slaying quests are a bit similar (but not nearly as irritating).
Combat is certainly difficult and is more of an action-RPG in that sense. Thankfully, customizing Geralt is pretty multilayered thanks to various forms of alchemy and crafting that can be done in the game. The combination of Signs and the "annihalation" bar later in the game can make it a bit easy at times, however.
Maybe even moreso than the first game this is one dark RPG, though it is thankfully a very well-humored, and Geralt doesn't get mired in a sense of hopelessness and beakness. The rough-around-the edges, brash tone of the first game are ever-present in the sequel, almost to the point where I wondered how the game maintained a hard "M" rating rather than "A-O." Women at times in completely nude (and extended) sex scenes with Geralt, language that will keep Sunday school attendees far, far away, and very gory images give this aplenty. I think Geralt's ever-present undies (hidden very skillfully during the sex scenes), and partial alternative swears (i.e. plough, whoreson) may have somehow kept this in the "parental guadance" range. Thankfully, the serious and well-written plot and dialogue keep the game from delving into trashy pulp fantasy fiction.
Noting such, this has some noticeably "grey" moral choices thorough out the game. Sure, there are some clear "good guy" choices to make, but I found many where I wasn't sure if I made the "right" choice. They tend to be a personal preference than a "right or wrong" decision, and some have a relatively large impact in the story later on.
Right now, I'm already impatient for the sequel
There are QTE's in this game, but it is thankfully optional. There is one QTE minigame in the prologue that is pure evil, that no other event in the game comes close to. Took me about 30 tries to finish (I could have skipped it, but I was stubborn).
