Also, and most importantly, the cost of running the MMO and hence the affordability of a flat fee for the game (supplemented by private hosting and additional in-game purchase) is carefully considered.
Remember when we explained why the Oort worlds are deliberately topologically flat beyond the standard generated region? This is explicitly because the servers are configured for running the MMO not generating worlds. Running an Oort world requires very different spec servers to generating worlds. We’re extremely targeted and lean on the server hosting explicitly to control and drive down a single value: the cost of a player per month.
This cost / player / month is the value we track and defines how affordable the MMO is to run in the long term.
