“Trion Worlds told us that the expansion was designed in response to the players who had already ‘beaten’ Trove to an extent. Without the freedom to completely change the rules and mix things up as the devs could during the beta period, they found that the logical conclusion was to add more challenge on top of the foundation that had been laid since launch.”
Players who log in beginning tomorrow through Monday will be granted special bonus gifts, including a Starry Shmeep mount, which sounds completely worth it.
