I vote for bullet points too. There's nothing wrong with keeping secrets, but I think sharing information is generally better for roleplaying; even if the characters themselves don't know each other, the players might get ideas for ways they could interact and relationships they could develop. On the other hand, it's easy to plan secrets and never see them come into play, in my experience.<br/><br/>I guess that's not an argument for bullet points over the full sheet... but I'm not sure I have one. The idea just sounds better to me.<br/><br/>But I'm biased because I like learning about other people's characters, and I feel like my concept was a bit of a mess so I'd be happier with a more concise and polished version in public.
