So I had some bloody stupid friends in the past. While I was trying to get a game started up for everyone to enjoy, they were messing about with the second controller. They deleted one of my most precious save files: Harvest Moon A Wonderful Life for the Gamecube. Now I was at the last chapter of this game. I spent a lot of time on it, I became rich on it, I had every animal, I had every building, every tool, crop, just god damn everything. Then they ruined it. Haven't felt the heart to complete the game since.
One time I left my copy of Pokemon Crystal in my gameboy player on my gamecube. I had one friend over. I went to get us drinks, heard a crash, came back up and the pokemon crystal cartridge was smashed to bits. My friend had pulled the controller too hard and brought the gamecube to the floor. Now let me explain this particular save file: I was only missing 3 pokemon from the pokedex. Every single pokemon I had was above level 60. I spent hours training every single one of them. That file was so precious to me. I had traded pokemon over from all the other games and I was only missing 3. 3!!!!!!!!!!!
My puppy also chewed my entire major gamecube memory card. it had 42 game save files on it. 42.
Excuse me while I go weep in a corner over my losses.
