I know there is already a 26 page thread on ME2 but my question is slightly off-axis. I was too busy playing WOW when ME1 came out but have since shaken that addiction. I am building a new system and very much looking forward to playing ME2 but was wondering if ME1 is worth going through first and if having that backstory would enhance the experience of playing ME2? I am somewhat of a completionist and feeling like I will be seriously missing out on something if I don't go through ME1 first.
