Back in probably 1998 I was playing a Nightmare LP game called Dragonrealms and after several months the game went down with no warning. Apparently there had been a massive loss of data and they more or less were back to square one. After a few months of literally checking the connection multiple times a day, it came back online. Nothing was retained from the previous version and there wasn’t much in the way of too many areas nor were all of the guilds back in. Most everyone else just played the guilds that were available, but I spent the next several months hoarding my exp because they hadn’t finished and reintroduced the guild I wanted to play (and guilds were the main source of skills available to a character, so think a cross between a clan and a class).
Basically, the way the game worked is as you gained exp you stored it, and then spent the exp on things like stats, skills, spells, etc, and then your level was a stat calculated from your total number of stats and skills.
I put just enough exp into my stats to get a few a levels and a just a few skills to make surviving viable, but the vast majority of my enormous exp hoard was being saved for this guild. As soon as the guild was to drop, I was going to dump all of my hoarded exp into it and be, by far, the most powerful member of that guild (which was a good argument for leadership of it, too) since no one else had the dedication or patience to wait on it.
Needless to say, since we’re talking “bad experiences” that didn’t happen. Some other player was in a pkilling mood I suppose, and kept coming after me, and after it being clear I would lose (and death on this game cleared your entire exp hoard… so I had also gone the entire life of the character never dying) I kept escaping, but some abusive imm (I suspect an alt-character of the player in question) kept transferring me back to that person. To this day I still don’t know why (other than sheer panic) I didn’t have the presence of mind to just log off after making my escape but after about a dozen repeat transfers, the other player finally killed me, erasing several months of exp hoarding.
I was not quiet about this and after a few weeks of trying to get something done about it, they finally deleted and banned me.
I check back in on the game a few months later and a similar sorta thing (minus the whole “losing months worth of exp”) happened, and then the playerbase went nuts over it and it was a big thing. I’m sitting there like “well, F me I guess, right?”
