Arcane
All it needs is the following:
[gigantic list of physically impossible to be coded inside the game features]
They already have ships, weapons, mechs and building
All they have to do is further expanded and tweak that shit (something with their team size and money is easy to do)
Factions also aren't complicated, they're pretty much a glorified friends list
The faction flag would essentially work as a flag in the system that would prevent any player outside that list from mining in said planet
And conquering a planets is essentially a Battlefield match of capture the flag
An economy system is something that would give them some hard work
But ultimately, with 1 or 2 years of development they could implement it
Megaservers now, might very well be to much for them
