It works in EVE because EVE has a balanced economy. WildStar being a themepark, it won’t (feel free to bookmark this and come back 6 months into release and tell me otherwise).
What I do find interesting is that WildStar, being an NCSoft title, is going to charge a sub, while GW2, also under NCSoft, does not. Now sure, GW2 is a sequel to GW1, which was also sub-free, but Anet never set out to create an MMO with GW1, while they most certainly tried with GW2. Pretty clear message NCSoft is sending with this announcement; WildStar is not a 3 week vacation.
Whether it succeeds or not I can’t tell yet, mostly because I’ve not been following the game closely and I’ve yet to read anything convincing about it one way or the other.
Now that I think about it, that’s a huge compliment to the game actually. Past MMOs have been easy; be it SW:TOR (4th pillar of fail), GW2 (living world of static zones), TESO (“we reskinned WoW with the ES IP, yo”), or EQN (SOE, parkour, boss red boxes, countless design fails in a single presentation) those games and many others were/are/will be DOA. I can’t say that about WildStar yet. Congrats?
