Like Ronin said, Eve is definitely not for everyone. Eve is a harsh game, if you do stuff it has consequences, always. Sometimes it can be good, sometimes it can leave you waking up in a medical clone and wondering what happened.
Also the most powerfull aspect of the game isn't the game itself, it's the community playing it. The game itself is simply a playing field, unlike in other MMO's where the content is there to provide entertainment and goals. In Eve, YOU set your goals, along with your corporation, and your alliance, and possibly your coalition.
Diplomacy in Eve is a very big part of the game, where some players in the right position can affect the lives of thousands of others by simply saying.. we're going to do this.
That is the power of Eve.
A good example of this is the recent 'attack' on the biggest tradehub of the game. A solar system in high security space, called Jita. Normally thousands of people come here every day, in freighters, industrials, jump freighters, whatnot. They come to deliver or buy goods, materials, ammo, ships, anything. There are hundreds of players in the game who don't even ever undock from Jita, living only in the main hub, trading goods people come to sell, buying them and selling them again on the local market, manipulating the prices on a grand scale. Trillions of isk trade hands here every day.
Think of the large commodities trade centers in the real world. Now imagine they're not just selling grain, or oil, but also nuclear warheads, battleships, submarines, etc. and there is absolutely no government controlling this arena of capitalism. Trade embargo's, cartels, thehy all exist in eve, and they do their shadowy thing behind the scenes.
Now.. back to that event.. this capital of trade was assaulted for an entire weekend by a group called 'The ClusterFuck Coalition' aka the CFC. This was a group of several large alliances that normally live out in the most lawless part of Eve, sovereignity null sec. Where they claim their own systems, and they are litterally 'the law'.
This of group of players, which is about 10000 people in all, a large number of them went to Jita, and started killing every industrial that came or went. Now, as this is high security space, when someone fires on another player, CONCORD will arrive and WTFpwn the offender, destroying their ship. Before they do however, it's possible to kill another player's ship. Especially if you have say 20 ships with big guns in them, and you all fire on that single defenseless freighter. Turning everybody into lovely explosions. ( this is known as 'suicide ganking' )
They were destroying freighters and industrials by the hundreds here, litterally. Now for size and amounts.. a freighter would be like a RL oil tanker, filled to the brim with 'stuff'. Now these were being blown up left and right, simply to attack the economy of eve. Why? Because they CAN. ( and some political reasons too. but mainly that one )
Ofcourse doing so, they will lose their own ships, so in order to destroy all these industrials and other ships, They need combat ships, in the thousands. Which all were destroyed by Concord.
Now.. imagine the capital needed to invest into such an endeavor, the logistics involved in getting these ships there, and preparing them for this campaign, and the drive that is needed to send several thousand players into one direction to go there and combine their efforts in this campaign.
THAT is Eve.. That is how big it is. And what kind of playing field the game is. In Eve, you could be part of doing somethign like this, or you could be part of some smalltime mining industry corp, selling their minerals for profit, these minerals could then be used by an industrialist, building ships, that were used in this campaign.
( On a side note, I tried getting a 'piece of the action' myself in this event. As soon as it was announced a month ago, I contacted people in the CFC to see if I could be one of their suppliers for their ships they would undoubtedly need. Sadly, several large industrial cartels had already beaten me to it. And I could simply not compete with them, because I did not have the capability to manufacture on that scale )
