A little story with Chrono Trigger. I rented the game but found it very hard, kept dying and so son. It was before Gamefaqs was a short URL away, I had no strategy guide, no idea how to do any sidequest (or that any even existed). A bit after we took it back, I got a used copy. On that copy, someone had a completed file where they had gotten everything, including this amazing sword called Rainbow that I had NO IDEA how to get at the time.
I was estatic. I could finally beat the game and get the full story I'd been wanting a conclusion too. Over the course of... I dunno, a long while, I'd gotten to the final boss and was struggling. I took it over to a friends' place to show him the game and show how creepy the boss was (and the dang noise it made--if anyone is familiar with Lavos' cry, yeah, as a kid that was... eep!) Anyway, afterward we went to do something else and I later found his brother playing my game.
No big deal... until I learned he had deleted all the save files, including my at-final-boss save with this amazing Rainbow sword I had no idea how to get. My dream of beating the game was crushed. I literally cried, bawled my eyes out for I don't remember how long. I don't recall if I ever even tried or touched the game again. I'm certain I did, and beat it at some point since when I got the DS version years later, I knew of all the side quests, how to get all the end game gear, and all about beating the final boss, but regardless. I don't have any other game that has such moments stuck in my mind like Chrono Trigger. I do still have that cartridge, I wonder if I should pop it in and see where I'd left things. x3.
