From an investment perspective, I'm not sure it's worth it.
173 worlds, 5305 current active owners(1 owner per team) if you subtract the 92, 139 current openings.
Roughly $15 per team after discounts and credit totals $79,575.
Working with the current state of HBD, the best you can hope for is 3 seasons per year on average. $238,725.
Not chump change but, once you start hiring programmers and consultants, HBD is a loser. Of course, this doesn't factor in the other games but I can't imagine they're bigger sellers either.
