Just Can't Drive Myself to Play

I've had Dishonored since it came out. Release day, I picked it and XCOM:EU up. Tried both. Enjoyed both. Yet, as the weeks went by, I kept putting EU in the disk tray, and letting this polished marvel languish in the case. I didn't really understand it, because I enjoyed both of the games, but had no drive to play this after the initial taste. Was I just not playing it right to really get its hooks in me? Is there something WRONG with me? D:
