Bernie-
these are great ideas and in the scheme of things, from the old days when it took six of us a year playing the board game to get a season done, its a fantastic leap from that point.
HAL, though not perfect, has come a long way, and all your work with that is appreciated.
the additions of the mystery cards, the Negro leaguers, and the idea of a random selected player pool, make it like a new season for real managers--you just don't know who is really going to show up.
If there is going to be a "live play" feature, How about the idea of being able to replay certain great world series matchups?
For instance: could replay the 75 World Series, one game a night, with live play.....you could sell that for sure. You could package a bunch of the great world series matchups, maybe 3 for $25 or something...
