>What other concepts?
Everything is taking place within the Solar system, which means large scale destruction feels a lot more consequential and tragic, because it's our home being destroyed.
Transhumanism and posthumanism. There are monsters out there and they used to be humans
Embrace the totalitarian ramifications of omnipresent AIs and computers, Sid Meyer's Alpha Centauri "we must dissent" style

>What other ways to implement power armor?
Power armour is Stormtroopers, but done right and scary (Jin-Roh style)
Power armour is a small mecha (Appleseed style)
Power armour isn't an armour at all, it's a cyborg body (Adam Smasher style)
Power armour is a mix between a tank, a helicopter and an infantry, it can equip small nuclear warhead as weapons (book-Starship Troopers style)
