Why did the NeX fail? Well, let's seeGǪ

1. It had no clearly defined purpose, and the one purpose it was superficially supposed to have (act as an MT store) was not fulfilled simple because it completely broke the fundamental design principles for such a store. MT stores work wonderfully because you remove pricing from the decision-making processGǪ the NeX does the exact opposite and therefore fails as an MT store.

2. It just introduced another currency that is completely unnecessary for what it does. It just piles on dead code. AUR was meant to be a more granular PLEX, but that granularity turned out not to be all that necessary.

3. It did not create a market due to its pricing structure and due to the mechanics surrounding the purchases, all of which does the exact opposite of what CCP claimed it would do GÇö as such it completely fails to integrate into the core gameplay. The idea was that people would buy NeX items and use them or resell them, but the market valuation of the stuff (and, once again, the pricing structure) ensured that this would not happen because the items were not worth as much as CCP wanted them to be worth.

4. It further enhanced an already existing perception that CCP were wasting developer time. The failure to create a store that would pay for itself; the failure to reuse existing code; the rush to get the thing out and the ensuing failure to integrate it into the game properly all pointed to this perception being right on the money.

5. It is far less capable of doing what it's supposed to do than the other market interfaces that already exist. Again, it just needlessly and uselessly piles on dead code that serves no purpose, and in the process, it threatened to break the industrial cycle that the game is built around.

6. CCP failed to do any expectations management whatsoever. They did not explain the purpose of the store. They did not explain the pricing structure of the store. They hinted at new gameplay and new professions, but failed to deliver. They did not test the store or gather any feedback, and instead did the early-alpha-stage testing in the live environment.

Plenty. Chief among which is that it doesn't integrate properly with the game and robs it of gameplay content.

The NeX failed because it serves no purpose that is not already covered (multiple times) by far better, far more mature, far more integrated features. The game does not need it. No addition to the game needs it. Trying to revive it is like trying to relapse into a bout of malaria.
