I thought the whole point of the trading in ED was that it was player driven.
Supply and demand fluctuates depending on trading trends. And that can be controlled by an organised group of players.
Agreed, this isnt as bad as pvp griefing by a long stretch, but if they could control the markets with their massive playerbase then they would exercise some influence on everyones gameplay.
Not as such no - a group of players can, over time, influence a local market. Goonswarm could certainly do that, it's true.
But equally, so can everyone else. And "thousands of players" is a tiny number in Elite terms. A million players might be more credible, especially as their influence here would be highly localised, & to have any effect on the game as a whole they'd have to move around a great deal. In the meantime, markets will recover.
It would be like handling 60,000 spinning plates.
And a quick background simulation "event" injection from the devs could rebalance things in an instant. Bet your bottom dollar the devs will be keeping a close watch on stuff like that.
