UK_John: I think you'll find nearly all of the hate is for the console version, which was a very bad port.
The problem is a console gamer will just say "I hate this game", whereas a PC gamer would say "I hate the conversion"
Hence, many thought the haters were talking about the PC version, because they didn't specify they were talking about the console version!
Minus, maybe, voice-acting critique - which I still think was very charming, and a strong point of the first game. My unrealistic wish actually is that we might get the main voice of the first game to return, as of yet... :-D
Meanwhile, as a PC gamer, my fear is that the console gamers' complaints are heard with keener ear than those of others.
I thought already the looting bit where a screen always had to be opened and closed with TW2 was a regeneration compared with previous interface - when a game on PC can only be enjoyed with a controller, that's to me the kiss of death to gaming enjoyment!
