Addiction is when you install a game, then you rob quite a lot time from reading and watching stuff, a bit of time from sleep and eat at the keyboard. That'd be, e.g., Sims 2, boring but goal-less and thus its gameplay can be dragged into eternity.
Now, obsession is when you install a game - and then rob time from smoke breaks, kill reading and watching stuff dead, rob and severely maim sleep and mark eating as unnecessary.
In other words, I installed "Icewind Dale" last Friday. RL, plz don't be waiting for me, I'll catch up...later. Somewhen. Well, one day for sure. *nods*
Yet, "Bleach" will be spared from reading and watching stuff massacre - mostly because Dale allows custom character portraits and thus I'm happily playing with all Bleach cast. %D
