The Witcher 2 - Preview @ IGN

IGN has written a very positive preview for this game. They talk about the much better choice and consequence,  the enhanced game engine as well as the better flexible gameplay. As usual, an excerpt, telling about the choice and consequences:

Three opening scenarios multiply out to a full 16 different endings. That kind of scope is staggering, when you stop and consider the potential routes necessary to bridge you from one point to another through the game world. In fact, during our presentation, we were privy to the entire game schematic – a tangled mass of plot points, missions and interconnected events and scenes that looked more akin to a circuit board wireframe than anything.
