Many times, while I know the hard rules of Shadowrun, I fail to put together a good combat that can be clearly described to the players. When initiative is rolled, we calculate our phases and then movement (base movement divided by the number of phases in the turn). But while I like the Mind's Theater aspect of combat in Shadowrun, I get too many requests to pull out a battle map, which becomes cumbersome to draw out with the scale that I need.
I'm wondering if anyone here has had similar problems and if there are good ways of dealing with tactical combat and movement in Shadowrun. Is a battlemat good, or is it better to you imagination?
