[MENTION=762]Mort[/MENTION], the discussion was for a DM who just tossed out character backgrounds unread if they were too long. So my whole point here is players who are engaged to write vs. DM discarding with no warning.
Sure, if the DM has put guidelines out there that's a different story. I don't understand them but it's your table. But throwing caveats on afterward does not change the initial discussion point - just throwing out a player's 10+ page backstory unread is a di-dastardly move.
Do you really need to understand it? Can you not just accept the fact that the way you play isn't the OneTrueWay™ and that if you have a different preferred playstyle and can't be flexible enough to work with the needs of some other gamer, that it's OK just to not play with them?
I require no backstory, but what I prefer to see isn't backstory anyway—I'd prefer to know something about what your character did in the last 24-48 hours or so before play starts than what his childhood was like. Also; I like little one-paragraph vignettes that players can come up with together wherein their characters had some kind of past interaction and actually know each other. This can be as formal as the Phase Trio minigame from FATE (which I like MUCH better than "backstory"), or more informal, but either way, it's likely to be more useful to both the player himself and the GM than a character biographical short story.
