I've done this with several games. When I first played FFX, I played it for about 10 hours before I found a good save point, and it was about 5 in the morning before I stopped. Resident Evil 4, I had just started the fourth chapter and I got all the way up to "It," and when I finally beat "It" it was like 6am. Pikmin 2, I just completely lost track of time, the sun had come up before I realized it was so late, that game is so fun. And I will more than likely be doing this with Kingdom Hearts 2 when the pre-order finally comes in.
