EVOs

EVOs is currency bought with real-life money and used to purchase subscriptions for upgraded or premium accounts or partial features of upgraded accounts through the hiring of specific Advisors for limited time periods. For example, the Administrator Advisor will extend the maximum queue size and allow access to the Overview page, while the Intelligence Advisor will allow the use of Scanners, access to the built-in Scout Database and remove advertisements. Other Advisors will offer the rest of the gameplay-enhancing features of upgrade or premium accounts.

Designer's Notes
It is up to discussion if - and how - we can implement ways to obtain EVOs in-game, in addition to external purchase through real-life currency. Also for discussion can be if we will eventually allow for "modular" purchase of the privileges of upgraded accounts, as mentioned above, or follow an all-or-nothing system, like Astro Empires. Also, under discussion is what will be the exact list of benefits of upgraded/premium accounts. It is in the game designers interest to build a game that is thoroughly enjoyable when played without any form of upgrade, while at the same time building a game that can be self-sustaining in terms of revenue generation so as to faciliate the on-going maintenance and development that a persistent game requires.
