Pretty simple question - the single largest part of my mobile gaming kit are my minis cases. My game would be much more mobile without them. But I love painting and using minis, and I feel like they add a huge amount of color and fun and clarity to my games.
Even using a stripped-down combat system, I still have the minis deployed on the map for marching order and to keep everyone straight.
What about everyone else?
If you play GURPS, do you use minis, or their virtual equivalent?
