There's quite a number of games I haven't finished. Normally i get near the end, get caught up with side quests or something, and then get bored. Ones I can think of off the top of my head...
Oblivion - admittedly because of the mechanics more than anything
The Witcher - got bored, basically. mainly with the combat system, which I didn't particularly like.
FFVII: Crisis Core - typical 'got bored while grinding for sidequest' here.
FFX - I did defeat penance, so I'm sure I'm more than capable of taking out the final boss, I just have absolutely no desire to anymore. That Penance run made me so bored of the mechanics I'm not sure I'll ever touch the game again...
FFXII - I got bored grinding for items to get the best weapons. That, and I'd lost patience with the battle system.
Disgaea: Hour of Darkness - the result of having a 30-40 strong party, and wanting to get all of them to the same level to complete the game. I just got bored with all the grinding. I did get to the final chapter though...
I'm sure there's others, I just can't think what they are...
