Traditionally it's the only thing that will prevent me from finishing a game. These days, however, I've started to get bored with a lot of these "non-linear," or "sandbox" games. I generally get tired of those about half way through and never touch them again.
Eventually I'll burn out on them as well. Oblivion is a good example. Great game, but after a while, the character becomes so powerful that he kills everything easily (but you don't want to go throw building up a new one) and you realize that you're just doing the same shit over and over. I got the Shivering Isles expansion, but never finished it. I doubt if I ever will.
