First off, Eve and WoW have nothing in common. I've played Eve quite a bit and I quit WoW just at the point where I had to start raiding all the time.
Seriously, nothing in common.
Someone once described it this way.
WoW is a theme park, where you are guided around taken on rides and given lots of things to do.
Eve is a sandbox where you have all the resources you need to build pretty much what ever you want.
The player driven economy works pretty well. It is extremely complicated to explain but it basicly boils down to this. Most of the resources you need to build the most expensive equipment is found in "0.0" or contested space where anyone can kill anyone and players can build their own stations.
Right now 0.0 space is split up by 10 or 15 alliances. Basicly a bunch of players have gone out there, setup stations and enforce their own laws through player might.
While they are out there they can build the biggest ship and mine the most valuable resouces but they are under constant threat from other players.
That is basicly Eve's "raids" is when two giant fleets go out and try and fight eachother for control of solar systems.
I hope that makes some sense because it always gives me a head ache trying to describe Eve to people who play MMOs. It is like trying to explain WoW to a Cheerleader... they just don't get it.
Anyway, my feelings towards eve are pretty mixed. It totaly kicks ass to have a fully player driven economy where every ship and almost every weapon were produced by players.
It is also cool that skills train while off line.
What sucks is that it takes a long time to make money and the activites you do can be pretty boring. Two examples are mining and agent missions.
To do an agent mission "Well" you have to spend roughly 5 minuets in prepartion to figure out what resistances and damage type you need to bring, between 1-10 minuets in travel to the mission site, 10-15 minuets of combat, 10 minuets of looting (no joke, it takes that long to loot, and that isn't even salvaging) 10 mins to travel back and turn in the mission.
And for all that you'll make about 3 million (level 3 missions) if you take into account your Loyality points which can be used to buy goods as well.
My ship and configuration cost me about 150 million.
And a side note here if I get blown up by players OR NPCs i'll only get back about 90 million of that total cost. Yea, ouch.
Mining on the other hand is a bit more of a team effor, usually you have a hand full of guys, sitting in space with mining lasers on a rock and every laser cycle (I think they last a minuet) they drag their cargo to a stationary contaier. Then someone in a high capacity ship comes by, grabs all the ore, and takes it to the station to refine it. Then after refining it they can turn the minerals it ships or weapons.
Literally those are two of the major ways to make money and neither are super fun.
If you decide to play this game really stop and think about what your goal is. See if you can't get into a 0.0 alliance and give the pvp a shot. If you want to make a trade federation and make billions good, go for it. But if you go into like I did, without an end goal chances are you'll end up quitting after your first couple ships are destroyed.
I keep comming back because I am in a cool mercenary Corporation. We'll see if it keeps my interest this time.
