Eve Online has been my first subscription MMO (Guild Wars and Runescape before), and has sucked me in for 18 months now. It has taken me from being a newbie to mining to missions to mercenary pvp to 0.0 pvp and now low sec piracy.
I hope to stay for years to come, but at this moment I am looking for a new alliance to join in 0.0. I need to build up funds in your space to purchase a carrier and other ships, but then I would love to pvp.
