I didn't care all that much for the X-Wing games' radar system, but I absolutely loved the 3D map! If we could somehow add a 3D map like that to Freespace, and then integrate wignmen commands and such to it, it would increase the tactical aspect of battles in FS immensely.
Just imagine, you're in the middle of a tough dogfight. You call for reinforcments, and just as they warp in, an enemy capship enters the area as well. Normally, you wouldn't have the time to figure out what wing is closest to the capship and assign it to them as a target. But with a 3D map, you could open it up (which pauses the game), check to see if the new wing is anywhere near the capship. If so, they'd be the best bet to go attack it. If not, you could see what wing would be best from those currently dogfighting, and assign them to attack the capship.
