I hadn't thought of that. That's true. But then, it's only really a matter of simple convenience at that point. You could just write your bio on a little piece of paper, and leave it next to your computer (or in your laptop bag) for easy referencing. I mean, at that point, it's probably worth it to have a simple saved bit of text, in-game, for such a thing. However, it would almost be pointless to go into super-in-depth "We'll help you write a relevant/awesome biography at character creation!" systems if literally nothing in that biography was going to affect/interact-with the game world whatsoever.
I mean, don't get me wrong, I think it's great what Osvir is thinking, here, but I'll take biographical details that actually impact my gameplay over ones I just get to pretend are relevant or "happened," anyday.
In this game, it seems like we'll have some early game choices to essentially use references to the past in dialogue to dictate what it is that happened in our character's past, to sort of shape our character's bio. In this case, especially, I think detailed bio-writing tools would be hindered a lot more if you have to pick one of 5 options to some question/description of your past (I grew up on a farm, I was raised on the streets as an orphan, etc.) and none of them coincided with your custom-built biography.
*shrug*. I'd love to see a game that helps you assemble a biography like that, then actually carries all those things through the whole game and provides reactivity and such. But, I'm not sure it would be feasible to have anything more than just an available history/lore reference for you to look at and comprise your own custom biography, manually. And, again, I'm not sure how feasible even that'll be once you start picking in-game biographical facets.
