Anyone complaining about this has clearly never played D2.
This is my thoughts summed up in one sentence.
I think a lot of players are seeing this with WoW eyes. But Diablo isn't WoW.
Within the Diablo community, trading outside the game has always existed, and has always been extremly popular with the community. That form of trading is there to stay. Blizzard can't eliminate that. And as a hardcore Diablo fan, I'd almost say that Blizzard would be stabbing their most devoted fans in the back if they did attempt to eliminate this form of trading.
And in my opinion, Blizzard are doing the right thing here. The outside-the-game form of trading is just a venue for the really devoted players who want to take the game a step further, which is the same thing that the various trading websites for Diablo II provide.
But there's no reason why players should have to explore fishy chinese-hosted websites and other dark corners of the internet in order to really involve themselves in the trading aspect of Diablo. It's far better if Blizzard aims to support that desire by creating a secure, easy to access, and player friendly system where players can engage in that form of trading without any worries.
And lo and behold, they are doing exactly that. Yay!
Righty oh then.
And no mods? And online only?
They obviously have everyone's best interests at heart here.
There can be no grey area about this. Bringing in real world cash into a MMO online economy could create rifts in the playerbase, and if it starts in D3, then where in the green earth will it end?
No. Just no. Keep this kind of thing out of games.
