Names in Huntercoin don't expire similar to Namecoin, but they are tied to survival of the associated "character" in the game.  All characters are wiped periodically in what is called a "disaster", after which any names can be re-registered by anyone.  So there is no way to guarantee that you remain owner of a given name, even if you actively try to do so (unlike Namecoin where you have to renew in time but can do that to remain owner for as long as you wish).

But yes, apart from that, I think Huntercoin has a lot of historical significance - it is just not collectible (apart from owning the coins).
