Not all RPGs will have their conclusion. In fact, not a lot of RPGs ever see their first IC post. Mainly because of the label of it being "dead".

However, the thing is, when is it considered "dead"? Some people say that after a week of inactivity, it's safe to say that it's "dead", but that can be averted if someone posts a week after. A month, at least for me, would be enough to say "yeah, it's dead, Jim". 

I guess it can be officially dead if the GM says it is, but what happens if one of the players decides that it's "dead", either through the inactivity or something else? Does one person's thoughts confirm that it's dead? I want to ask this because I have various people using various rules of thumbs. So much in fact, that I can't even use a simple poll machine to judge the appropriate answer. I wanna hear from you:

When do you consider an RPG to be "Dead"?

For me, it has to be a month of inactivity from both IC and OOC before I can consider it dead, and even then I'll try to revive it after a week to see if it's truly dead.
