Games are an escape from reality, so why are we letting operational reality get in the way? We don't have to any more!
You imagined a game with a persistent, fully destructible world. A combination of PvP, FPS, and RPG. It will have have millions of entities and thousands of players.
Focus on the game logic and let Aether Engine and HadeanOS take care of the scaling.
You want your game world to grow organically, support huge, organised PvP battles, and maybe even a world record. Its going to need a huge effort from your operations team.
No, it won't - Aether Engine and HadeanOS handle all the distributed server operations.
