The Witcher has a good athmosphere, and the choice and consequence regarding the conflict between the Squirrels and the Order are very well done mechanics-wise.
That said, the combat was uninspired to me, even on Hard, where it's just a matter of knowing what to do rather than how to do it, the sexual content was kinda over the top, and most side-quests were just about killing X and taking Y stuff from their corpses, and you even had to read damn books before you could figure out that well, yes, the head is here (it is justified a bit by the fact it's Geralt's job, but still).
Another bad part for me were the characters. Not a single one was interesting, starting by Geralt whose voice actor sounds like he smokes a hundred cigarettes a day (well, English version at any rate) and who can declare undying love to Triss/Shianni 5 minutes before
and after boning another woman. Special mention to the dwarves with exagerated Scottish accents and beards.
Finally, the game tries way to friggin hard to be ''dark'' and ''mature'', it's even worse than Origins. Every single person is a murderer, as rapist, a drug dealer, or just a plain ol' monster in disguise, and the leader of every factions just want to kill as much people as possible. It's very difficult for me to care about somebody or their cause when they and their opponents just murder people for teh lulz of it. There's a neutral option, but I felt like it was my only choice because the two others didn't attract me the slightest. I certainly would have stopped playing had I been forced to choose between the two.
Wow, didn't think I disliked that game so much
It's still not bad per se, but these things held back my enjoyment enough for me to force myself to play once and then free up 14 GB of drive space the hard way.
On topic: Still playing DOW2 Retribution, and boy did Relic deliver this time. I like Steamworks more and more (goodbye NAT failures!) and the campaigns are just so well done, Orks being an especially fun ride. Get this if you liked the original in any way, shape or form.
