I had one specific memory card I kept all my RPG data on. I had either completed or near completed game saves for, Parasite Eve, Valkyrie Profile, Lunar: Silver Star Story Complete, Final Fantasy Tactics, Breath of Fire III & IV, Final Fantasy V, VI, VII, VIII, Saga Frontier 2, Legend of Legaia, Star Ocean: The Second Story, and Legend of the Dragoon.
A supposed friend of mine swiped the card when he was at my house and I thought I could trust him. When I later found the card at his house the next day. He had cleared everything off it. I'm talking hundreds of hours of data, gone. Just to be replaced by replay videos for Gran Turismo 2. Then had the gall to lie to me about where he obtained the card.
Yeah you just pick up a clear green Mad Katz memory card with your friends name carved into it at any local pawn shop, I do it all the time.
To this day 11 years later I still haven't even gotten a quarter of that data back. I think I have 3 games completed. I am still pissed at him for that.
On a side note that same SOB boosted my Final Fantasy Chronicles and Mega Man Legends, about 6 years ago. When I loned them to my brother. Yeah this ass hat is my most favoritist person on the whole freaking planet!!!
Sorry for the rage. It just gets my blood boiling to think about that.
