While the Macross Plus fan in me wants drone Aerospace fighters, I just dont play aerospace enough.
The 'SLDF with Drone defenders' in HBS battletech really stuck with me though. Like, a big beef I have with ground vehicles, especially hovercraft, is losing crew in campaign games. As soon as immobilized, the crew are dead the next turn baring some crazy circumstance, and BOY did crew costs wrack up trying to play a vehicle campaign. But robotic vehicles lets me march many Pegasus hover tanks to their doom, without feeling bad about sending a dozen crew to their death each time a Pegasus Lance engages in close contact. That, in turn, lets the experienced crew wrack up XP from longer ranged tanks, while the Pegasus team runs interference with no fear of casualties.
