Something I think would be cool- when you die, you leave behind a tiny grave that, when you press E nears it, tells who died and how.
And you get a beacon back to your grave(which you may turn off).

Heh, there would be quite a few of these around the world very quickly I think ;)

Well, I figured it would be, like, it disappears once you die again.

If the graves are permanent then yes the world would get covered very quickly. However you could make it like a treasure. A player dies a grave appears and gives random treasure when searched. ( this is not to be confused with dropping a corpse and all your items if you die ) If the original player gets to it first they get an even bigger bonus.
