@Misao: In Confessions of the untold creator (something like that) I rescued a moogle from a dungeon where he was trapped for so long. So when I turn the psp off (put it into sleep mode) i always do it making sure that this moogle, which is currently following me, is face to face with another moogle on the map. Figured he deserved some company after all that.
I only saved every so many days. On day 80 i was turning the psp off into sleep mode when i wasn't satisfied with the moogles positioning, so i held the power button in the middle of turning it off thinking it would by me a few extra seconds. Then all of a sudden my psp actually shut off entirely... -_- So i lost all 80 days. I remember being so upset about losing that 'massive amount of time'. Now on day 1000 it doesn't seem to bad...
(i should mention i did that the moment after waking up)
