Eve is an incredable game, can become very consuming though. Played it for 6 years but went inactive good few months ago. Used to run few pvp corps; The Priory and Spartan Industries.
Keep thinking of coming back but blobs and capital ships just ruined most of fun for me.
I remember the Priory, they were a good corp! Personally i was in Tyrell Corp for 5 years before i gave up on the game. It takes a big chunk of your life. Any PvP game will do over crap like WoW etc. If you have the patience for it though, Eve is the best of the bunch
As for cost of the game, if your hardcore, the ammount of money you generate in game can be used to buy time cards, so you play for free.
and blobs are avoidable, but if your a one man band with no alts, not so much. Train to be an inty pilot, cheep and effective, 10 of you and you have an awsome battleship ratter hit squad
peace
