Prologue: The universe is Diablo II. The server is Europe, which usually has the nicest possible fellow players. The game I'm in is a mule game. I'm a paladin. My mission for the evening? Either to rescue the old sage Deckard Cain from the village of Tristram, which has been sacked by demons and set afire, or to find all the waypoints (save spots) that I'll need to do it elsewhere later.
Scene 1: A Cave
My paladin is standing in there, next to the exit, doing nothing while I'm fetching myself a bowl of soup from the kitchen. As I'm settling back into my comfy chair, I see another guy run past and out. Then I hear someone declare me an enemy. "Hmmm," I think to myself. "Maybe I better go back to town while I eat."
So I make a portal. And just as I'm going into it, the other guy comes bursting back in, I hear a clank as something hits my shield... and then the screen freezes.*
When it unfreezes a few seconds later, I'm safely in town. A few seconds after that, the other guy loses his connection to the game.
Scene 2: Some Dark Woods
I'm proceeding at a leisurely pace with my evening plans. Someone else had already found Cain first, so I was just wandering around in the Dark Woods looking for its waypoint.
The other guy comes in. Based on how long it took for him to come back, the freeze probably crashed his computer.* He immediately declares me his enemy.
I sigh with some annoyance and leave the game.
Scene 3: A Marsh
I was back to looking for waypoints again. Originally I thought I'd just proceed in a different game. On the one hand, there were 7 other players in that one (all of them just standing there doing nothing), which meant nobody else could come in. On the other hand, there were 7 other players in it, which meant all the monsters would be a lot harder to kill. Also, because it's a different game with a completely different map, I'd have to start my waypoint searching from the beginning.
So I came back to the first one. I'd found the Dark Woods - it wasn't far at all from where I left off, and had gone on to the next area (which was a marsh).
Other guy comes in again - just as I find an Experience Shrine. These things are rare and valuable, because it means faster levelling. So I decide to use it. To be safer, I go to a cave that's not part of any game quest and has no waypoints, and therefore nobody ever goes there.
Scene 4: Another Cave
Other guy declares hostilities (no big surprise there). I actually look him up this time to see what exactly I'm up against. Level 91 paladin. I'm Level 11 (read: toast). But hey, I'm in a nice safe cave, right?
Just after the shrine wears off, he suddenly appears in the cave, teleports over (a sorceress spell not normally available to paladins), and kills me in one blow.
Let's stop and review here. First, he's 91 to my 11. Second, he's quite obviously decked out on high-powered items, because he's a paladin that's somehow using sorceress spells. Third, he's obviously outfitted with a map hack if he's able to find me at all, let alone so quickly. And he's just spent the better part of two hours stalking me, a total non-challenge who is trying to stay out of his way, just so he can kill me in one blow.
I resurrect in town and say "compensating for your tiny penis or something? :p" Then I leave the game before he can reply.
Oh the wave of fury that rolled in right then. He was so pissed I was shaking, and it didn't go away for like 20 minutes.
Epilogue: Saving Cain
It's virtually impossible to save Cain in a public game. First, it's a very low level quest, which means most people who make games have already done it. Second, Cain is useful, so mule games want him already saved. Third, even in games where he isn't saved when I first arrive, he will be by the time I find where I need to go - because everyone seems to have a Cain-saving hack.
Thus, having collected the waypoints I needed, I spent the rest of my evening in a private game (that is, with a password). The enraged shaking eventually faded enough that my own emotions on the matter could come through, which mainly involved lots of snickering.
And Cain was saved. Hooray. :)
