The game needs to cater to all play styles.
Alpha needs to be profitable enough for new players to join (spend $) and learn basics and get resources
But not easy. Or bottable. Needs red spawns, roaming observers.
Beta needs to be far more profitable, and far more dangerous. Enough for a newb to want to risk bots for reward, die in PvP, and still want to come back and risk it again. And Beta needs to be open, the only way corps should be able to shut it down is by presence, not lockout mechanics.
Gamma needs to be the be all end all. Highest investment cost, best rewards, resources, industry. It needs to be defendable, but not unbreakable.
These guidelines cater to all players at all levels. It's what the game needs to survive. Currently Alpha is too easy, Beta is too risky for rewards, and Gamma is not defendable.*
*based on an actual decent playing population which the game does not currently have.
