holy shit this sounds awesome hahahaha.have a drone follow you from a TPS angle and feed the video into a VR headset. Bingo!
Most RTS's do work like that actually.
Line of sight is an important variable for RTS units.
To be fair to them, RTS games generally give the line of sight for all controlled units, rather than just the one that's currently selected. That'd be a pretty weird system but maybe it's been done before?
