Just about the only method of attaining some form of immortality open to real life is to pass your legacy down to your children, and then hope that they continue to live up to it once you die.

Not so in a roleplaying game! In the fantasy genre, you can transcend mortality by becoming undead, or through magic (or both), or perhaps even by ascending to godhood. And within science fiction there are also numerous possibilities: brain uploading, cyborgification, anti-agathic drugs or technology, and so on.

Still, having kids who want to maintain your legacy isn't a bad idea, as accidents can happen.
