>Eve is hemorrhaging accounts and the player outrage from the aftermath of their attempts to directly monetize the playerbase beyond PLEX accounts make them a VERY bad example to follow.
I would argue CCP's issues are more with their marketing and customer-facing people than anything else. Valve did that with TF2 hats(some cost $20 or more to buy), and didn't have nearly the same level of fallout with it. Blizzard's done the same thing with purchasable vanity pets and in-game mounts, and hasn't had really any backlash from it.
CCP was charging US$70 for a virtual pair of jeans, then made forum posts trying to convince people since people spend that much on actual clothing, they could charge the same thing for the virtual item. The userbase, predictably, wasn't happy with this idiotic argument, and the fact that a LOT of development time went to these features versus things that actually impacted the player's experience.
