With the upcoming achievement system, we should chip in with ideas. Some are found on this blog post.
Here's what I thought of so far:
1- Achievements for interesting deaths.
2- Achievements for side quests.
3- Achievements for challenge games.
4- Achievements for other odd things.
5- Achievements for anything of notice showing up on an .flg.
1- Anything more interesting than getting below 1 hp, bleeding to death, etcetera. Choking on your own vomit while paralyzed seems like a likely candidate. Certain things that might require a bit of additional programming (i.e. things not already present on your cause of death as shown on the highscore) could be added, like getting killed by a former companion.
2- Puppy quest, Kherab's quests, etcetera.
3- Lithium, Brass, Brimstone, Ironman, you name it.
4- Killing and eating the cute puppy comes to mind but a lot of interesting things could be cooked up here.
5- Self explanatory. Some are redundant with side quest achievements (Blup, puppy, AKW quest), some are not (getting the trader's guild to owe you money).
