I will not base my character off of anyone's else regardless, so if it helps/ then cool. I would like to know basic info like appearance and function so that we can follow each others' stories better. Would not care to have 1/2 the intro posts be rehashing descriptive/story info every time new characters introduce. But then again, I have no idea how you fine folk are going to write :)

Now it will get finicky down the line (if/when) characters meet each other. How much do we want to know about each other/ what don't we want others to know.

I think your middle ground option would be for everyone to indicate what they would like listed on their CS listing. Or just flat out leave out the fine details/back-stories/terrible secret pasts, and that can get sorted out in the RP. Either way I will not meta-game anything I see,
