They aren't close to tapping the customer base for this game. They aren't trying to.
Fox makes more money promoting hundreds of things than they make promoting HBD / WIS. And they don't use this space to promote anything. One ad on the top of a page that maybe 10% of the people playing this game see once a week generates a few dollars a week for Fox.
If they were will to invest in the game, there are things they could do to make it a more reasonable game to play for more people. There are a few days you MUST have internet access & time if you want to compete. Miss the key coach hiring days, and there's a good chance you've set you team back. I'm sure people check out then. Easy enough to fix how the game works, but it would take a bit of programming.
Same for FA negotiations. The current system is about as complex & non-user friendly as it can be. No reason we couldn't get immediate replies from coaches or FA. No reason for there to be a hard cut off date for signing.
And the draft. No reason they couldn't post the draft class the day the season starts. I've been on vacation or traveling more than once during the 1 week we get to rank players. Sucks. Would be very easy to walk away from the game, or at least that team right then. No reason to not give us 2 months to rank the players.
For some reason, way back when, someone decided this would be a batch game. This game was developed by what appear to be A+ programmers & baseball fans/geeks and D+ web programmers.
What's I've seen posted before, but not recently is that, despite all of the flaws in the game and the lack of updates or improvements, HBD seems to be, without too much debate, the best baseball simulation out there. If I found a better one, or one almost as good, I would have jumped ship at least a year ago. One more reason why it's understandable why Fox doesn't invest a dollar on HBD.
