An RTS where you could only swap between FPV views of each of your units would be fun. Or at least different. Savage II but there is only 1 player per team, and no overhead view. And you can wrench control from a bot at any time.
Sacrifice is a brilliant RTS where the commander (a summoner mage of sorts) participates at the ground level.
Isn't this Mount and Blade?
It was the dream but any game that tried was always disappointing.
Battlezone and battlezone 2 [0] were great for this. Many hours lost, even if bz2 was a buggy mess on release. It was also one of the first faves to really have a missing community.
