The first times i played, i was just overstrained. But slowly, as i read the rules another time and watched the ingame-videos, i got a grip. I realized that the rules of the common card games like "Magic" are likewise, turns are divided, there are different card decks and so on. At this point the game turned into pure fun. It´s very athmospheric due to the very good soundtrack and it´s Witcher-World. The only thing i experienced is that the AI could be more pushing and biting you.
The shooter genre is not my personal fav-choice, but it has good games to offer. That one here is a classic, a cult-classic, whatever you want it. ;) Three classes, a lot of options, stealth, brutality, hunting, you know it. And it was fun to play at it´s time. Today it´s still fun, but not as much as in my remembrance. I guess i was a few years younger and had other demands to games. I played it today and i quitted sooner than a few years ago ;) For a quickie the game can get me anytime again, but it will be just that. I dont say: "Dont buy it!", but i dont say the opposite, though. Make your own decision, just for nostalgia and about 5 bucks you can´t do much wrong. Except save five bucks for another game. ;)
