What do we want in a character sheet...

Well, Cyberware and personal weapons, as well as most of the protective gear should probably be mentioned. Then if they have any important connections, the type of an area they reside in... bit of background is a no-brainer more or less, unless we want our characters to be in the dark about one another. But we all can keep OOC information from interfering IC or we wouldn't be doing this thing, so it is better to just have it there, makes tying them up in the story an easier task.

And we must not forget that cyberpunk, like all the punk genres, is all about [i]style[/i]. Appearance has to be pretty detailed, I believe. Or images can be brought in, if not both. That's my two cents on it.
