I recently started grabbing all the old Thunderstone sets, downloaded the App for my Iphone (before the recent update.) and saw that they had a custom card maker that was available. (removed in the recent update which I won't do now.)
I've looked around a bit here, but haven't seen any home brew expansions. I'm wanting to work on one that integrates a video game I played a lot prior to my board game addiction. (POXNORA)
One of my first attempts/ideas is a monster group Bones from the Forsaken Waste faction:
The Bone Elemental
And the Bone Mauler he "summons"
A few more are in my gallery.
I would love to see how others approached this, and any guidance on how to cost things. General balance guidelines that anyone may have.
Thanks in advance for any direction, and help.
