So, I was thinking about planetary conquest one night, and I recalled the interesting game called Dragon Dice. One of the things I enjoyed about Dragon Dice were two things: 1) Each die represented a unit. When you had an army, you rolled all the dice, and you used the different results for different effects. One of which was... 2) Terrain Dice. They had a D20 that had different effect icons and a value which indicated range from target. Movement icons allowed you to change the facing on the die if they outnumbered your opponent's.
Imagine having a pool of dice, each one representing a lance or company and objective dice that represented key places near a capital or on a world.
I know that I've wanted to see various aspects of BT tackled in a game format of some sort, just like the above. Catan for world- or region-building. A Cities & Knights add-on to have the occasional pirate raid.
But, I know there are others. What games have you looked at and thought 'Oooh! I could probably port that into BT for some fun way to cover X'?
