Well, in defense of our addiction I think part of the reason behind why we play so much is because it can take quite a long time to do things!
Last weekend I decided to go get some meta alloys to unlock the meta alloy HRPs. I located a site with ripe barnacles, then went into outfitting to swap a few modules around to shorten the trip and make some space and also buy an SRV. After a good few jumps I arrived and landed at the site and started shooting barnacles, I needed 16 MAs but the SRV can only carry 2 at a time. So after a few relogs and trips back to the ship I had my 16. I then had to find another station that sold a certain commodity needed for the unlock. I then needed to visit a mat trader to juggle my mats so I had everthing else I needed. I then had to visit a tech broker to unlock and buy the MA HRPs. Finally I had to return to the system I started in to enjoy the limited benefits of the MA HRPs in an AX CZ!
So the above took me 2 hours. Don't get me wrong, I enjoy all the flitting around, its all part of the fun, but it's also a big reason behind why we end up playing for so long.
