I regret having wasted money on Witcher 2 (or at least, having bought it on release). Graphic extravaganza aside (though it doesn't look much better than the first game on my rig), it's the most disappointing game of the year so far.
Terrible inventory, terrible combat, butchered alchemy, and only five monster types in the entire game (harpies, nekkers, rotfiends, bullvores, gargoyles).
Story and CHOICE AND CONSEQUENCE!!!111! are admittedly nice, until you realize that aside from one totally different chapter, you're as much on rails as any BioWare game.
It's as much mediocre as DA2 is. I doubt I'll ever replay it again.
