I think it's good to remind players of the importance of not dismissing the RP side of the DR. Yes, the current game mechs may diminish the importance of death for our characters, so we end up with strange situations in which you come back to the living for a rematch after 5 minutes. Its relevance should not be undermined. It's death after all so, in general, characters should do their best to avoid it, if they die within RP they should take the time the settings establish before coming out. No, the settings do not establish a quantity of hours or days but it does state that it's a huge place (hint: "
Realm"). The fact that it's not huge at the moment can't overweight its RP sense.
You can add your own RP touch like "I'm too weak to cross over yet", "Every time I enter the death realm, everything's different (as if you "landed" in a different part of it every time)", or "The DR is like a dream or nightmare you forget five minutes after you wake up so everything's a blur every time you come back". I don't think there will ever be an "official explanation" prior to having a really huge DR that will actually force you to stay there for more than 5 minutes but until then, for any RP purpose, we should try to be consistent with the settings. That said, this we can all agree with: if you die in RP, avoid instant respawning.
Now, the meaning of death talk is probably as old as the PS forum though the search engine hasn't allowed me to find the very first thread about it. And I'm curious now

. So, yeah, I'd like to re-open that dreadful door and I'll appreciate any links. I found
this one, but I doubt it was the first big talk (although it does make some very good points). Again, I think it's important to come back to this subject since new players and new forum members come to our community every day and everyone should be aware of these discussions before reaching conclusions based only in game mechanics.
