With all the info about the DUST 514 console MMO set in the EVE Online universe, and player-run banks in the game mirroring the financial meltdowns we read about in real world headlines, we didn't have much time to look over something that's quite unique to the game. EVE's developer CCP Games releases "Quarterly Economic Newsletters" (QEN) which show the various ways in which player actions affect the game universe, given its player-driven economy. The QEN for the second quarter of 2009 has been released and gives us a snapshot of player activity in EVE's single-shard world.
When you PvP in EVE, someone's going to win while other ships are obliterated. Someone manufactured the ship, modules, and ammunition you used to take down your opponents, likewise the ships and modules you destroyed were also created by other player characters somewhere in the New Eden galaxy -- players who have mined and refined, bought and sold materials needed to build the various items put to use by EVE's pilots every day.
