[Actual Play] Do other people find them hard to write up?

[Grail]

It depends on the verbosity of the writeup. I've in the past written up every session of a game and used it as the recap at the beginning of each new session. At the end of the game, I printed it up, bound it and gave it to each player as a sort of pseudo-novel.

As to how I manage, I just use my memory. And the quicker I do it, the better the accuracy will be.

Having 100% accuracy is, IMO, not 100% required. Just as long as you get around 80-90% you're fine.
