I just started friday. I played wow for years and can tell you that the only thing that's comparable is that they're both MMORPG. And they both have an economy, PVP and missions. That's about it.

It's a far more complicated game and not very carebear friendly. A big aspect in PVP is camping warpgates and ganking anything that comes through. Which means you can lose a lot of money by going to lower security levels. But obviously, that's also where most money is made(correct me if i'm wrong)

If you like putting effort in the game and spend half your gametime reading about what is what etc, then go for it It seems that there is much less need to play with other players in EVE aswell.
