Actually, and this is horrible, the reason why I don't think it's looking good is because.. it's made by a polish, untested company. I AM A RACIST! WAAH!
Seriously though, I get a lot of eastern european titles that I have to review, and so far 90% of them have gotten horrible reviews because of mainly one thing: incomprehensible translations. Especially the russian games are atrocious. Sometimes the dialogues doesn't even make sense, and all the humour, emotion and suspension disappears somewhere in the hands of a crappy translator. I seriously suspect they use Babelfish to translate some games.
Who knows, maybe Witcher will be one of those rare games that proves me wrong. I sure hope so.
