[insidious]

Played it before and it's an awesome game. Can be pretty much as casual or hardcore as you want to make it, though whether you have fun or not entirely depends your attitude towards the game.
I'm not sure if I would be up for playing again just because it becomes a gigantic timesink for me, but I definitely recommend it. Used to be a Market Trader/Small fleet PvPer back when I played making mad cash and space PewPewing opposing corporations in order to retain our corps hold on an area in nullsec ?
