Oh hey, THIS game. I have a story about this game.
So, back in third grade, I would play Spybot every day during recess in the computer lab. And it wasn't just me, actually, there were about ten to twenty people who would also play on their specific computers, which had their personal saves. This game gets really hard towards the end, and I was the only person who had managed to unlock the final boss, though it took almost the entire year to get there. Everyone else had yet to beat the level that unlocks the final boss, and despite my best attempts, I couldn't repeat my victory on another person's save. However, I would never wind up finishing the game. I had to move. Three weeks before the end of term, I had to leave, so shortly after unlocking it. So, on the last day, I said goodbye to my save file, and officially bequeathed it to a friend of mine, because I didn't want the beaten penultimate level to go to waste.
I never spoke to him again, and really hope that he managed it within the following three weeks.
