BlackMageJ: In an online game (especially an MMO or MOBA), automatically ban anyone deemed to be using anything other than the optimal strategy. The algorithm used to determine the acceptable strategy will be constantly changing, and will at no point be published or explained.

Actually, does it count as evil if it just saves the other players the bother of doing it themselves?

dtgreene: How about (going back on topic here):

Autosaves that specifically save whenever you are at low health or otherwise in danger. (In other words, instead of triggering regardless of other stuff, it specifically triggers at the worst possible moment. In other words, instead of being just poor design, it's malicious design.) Also, make it so that there's only one save slot, so the autosave wipes out your carefully placed manual save.

I could point out that Ultima 3 actually autosaves whenever somebody in the party dies.

dtgreene: One thing I thought of that happens in some literature, but which I have not actually seen in a video game.

Game introduces a major character who is a lesbian (and I specifically mean lesbian here, not bisexual). Said game then either:
* Kills off this character, particularly if done in a stupid way (like by some stray bullet that wasn't even aimed at the character and wasn't from a major villain), or
* Puts that character in a romance with a man.
