There is an interesing interview with a witcher designer at IGN. (Spotted at RPG Watch) And they don't like Oblivion:
You gotta like those guy.Michal Madej said:Gothic despite it was open-ended, still it was story driven. Oblivion was not story driven at all.
I didn't like Oblivion at all. [CD Projekt] had to play the game, we had to find what was, why the game was so popular.
We believe Oblivion was so popular because, first of all, it was very well known brand. Second thing it was very popular because it has really great visuals. And also my opinion is games like Oblivion are dying because people who want to play open-ended games, they're playing online games. Playing Oblivion was like playing World of Warcraft without any other players. For me it was boring.
