I don't know any of the people on the podcast but the reason I said they didn't seem like baseball fans was the comment about 162 games being boring and a need to speed play the games with features like player lock. Millions of people spend significant money to sit for hours and watch baseball. Those folks on the podcast seem more interested in getting it over with than enjoying the experience. Baseball is not a game for people with short attention spans. One of them was talking about how many cool arcade features were available for his created player in NBA.
For me the best part of mlbts is the realism of the game in franchise mode. It is like playing a sim with realistic results while watching at the same time.
If Owen Good is the exception then I stand corrected but there was little on that podcast to indicate a significant interest in baseball.
