Depends on what helps the story or the character more.


Old people are good for conclusion and revelations. Young people are good for discovery and learning. The difference between the two at the core is justification: Young people know jack shit, even when they think they do. They can be smart and right...but still know jack shit. Because it's all based on theory, rarely practice. One again, that dosen't= wrong. It dosen't means that, it's all fine to write a paper sending a rocket to the moon.

Different sending a rocket to the moon.


Old guys are justified in their conclusions...but they can still be wrong. That real world application dosen't equal a working life. You can be right that swindling old folks makes you rich, dosen't make you any less of a cunt nor does it make you any less unhappy with your lose of integrity. 


I like old guys because typically old guys are good as player to GM interims. They know about the world, even have regrets about the events in it. It's a good way to "rewind" bringing other characters who may not have motivation back with you. Making them see events, judge a personal morality and see the story in it while making them pertinent because...hopefully...my character would be pertinent to them.

but hey. I like being a young guy who hunts big titty anime girls too. So, tomatoe, potatoe.
