I used to play quite a lot 2 years ago. Then I had a break of over 6 months once. Then I played again. After that another break of 6 months. And now, since .86 gets released, I'm just having breaks of maximum 2 months. (Lost quite a lot stuff because of my breaks. But some ships survived those 2 years.)
It always pulls me back. So yes, you could call that behavior addictive in some way.:D
And about the drawing: I'll try now. But I won't show it anyone, unless I'll like it.:)
Good thing it isn't as addictive as WoW. :| ... or is it.
