I'm all for new features. The way I play the game, it is pretty realistic and I am very happy with the results. I would love to have promotion and relegation in the my personal baseball universe.
That being said, a game has to be build on a solid base. I would rather Markus make "Wolf-baseball" very solid before branching out into European-style leagues. So far I've trusted Markus' ability to keep making the base solid while adding a complement of new features.
So everyone is right!
