I tend to play about 40-60 games of a dynasty (have played a whole season before, I think it was 3 years ago) and them simulate till the end of the season. By that time, I either do the same for the next season, or get sick of it, and concentrate on online play. I think I will try the suggestion of playing one game with the #1 SP, simming to the #2s 2nd start, simming to the #3s 3rd start, and so on. I like this idea!
Usually I get tied up in Fantasy Baseball and summer activities and just do not get too far. When it comes to NCAA football, with the cold weather and all, I play at least 15+ years of a dynasty. This new way to play a season may bring some of the nuances of a dynasty back to baseball games for me.
