All I'll say is this;

Obviously character development is paramount. I've said this myself in countless RP's. Especially in Sci Fi. Where great Sci Fi is all about the why and who. 

That said context is important. 

A 10k ns is nothing compared to an IC sections with hundreds of pages. 

I am not going to discuss the issue further unless the gm has something to ask of me. 

Instead I'm going to focus on telling my story IC and sharing and creating stories with the other players.

Have you actually read mine or terminal's sheet? 

You're saying it's daunting. 
I for one think a well.written ns makes me excited to write with that rper and interact with that creation.
