Did the scope of what you are doing with Eve isk grow beyond what you originally envisioned? Was that responsible for the longer timeline? In some ways it did grow yes, but in other ways the overall scope also shrank. Over the course of the project we've implemented a lot of different systems and tried them out. Some we keep, others remain in the game partially, while others are thrown out entirely (though we always learn some lesson while implementing them). This is all part of the iterative development process that we like to use here at Arena Net.
