Have you ever gotten a considerable way into a game and then restarted because you didn't like how things were progressing?

One time I got about halfway through Deus Ex and then realized I didn't like how I'd been doing my skills and augments so I restarted from the beginning. For those of you who don't know, the original Deus Ex is quite long to play through, so that was many, many hours deleted just so I could redo my skills and augmentations.

How about you guys?
