Earthrise Interview

A bit more information about Masthead Studios' post-apocalyptic MMORPG Earthrise can be gleaned from a new interview with CEO Atanas Atanasov over at MMORPG.com.
The game follows a sandbox approach. MMOs like EVE and Ultima have built their success on this format where other games have failed. Why does the sandbox approach add so much to the longevity of a game?

Atanas Atanasov: So far MMORPGs have figured two proven paths of keeping players interested in the game long term: constant addition of solo-able content or raid challenges that players must overcome and then wait patiently for more, and the sandbox approach where players have to find their own niche and approach to the environment and their challenges are set not by the game designers but by the combined actions of all other players. The latter approach's main strength is the cooperative notion that the game is indeed shaped by the players. To many players, the ability to change content to their personal or collective will is much more important than the chance to experience more and more content. The sense of involvement and power to create and change can invigorate and keep players glued to the game for years to come. Games like EVE and Ultima have both succeeded to achieve a stable and exciting environment for sandbox gaming and have been some of the inspirational sources for Earthrise as well.
