One thing that is pretty clear is that people like these dice, and it has been a successful promotion of my blog. It has also raised awareness among the Battletech community, which is an important part of my target audience.
I'm getting requests for more dice from people I know handing them out to other gaming groups, so I know the word is still getting around. This cost me $200, but it has done what it was supposed to do, and it been nice to have something I can give out that gamers appreciate. I would do it again, and my supply is running low, so I'll likely need more for next summer.
