I boggle at people that use LARP-writing systems that don't make gender easily swappable; except when writing a game set in a historical setting or such with strong gender roles, it doesn't make sense to me to assign characters strong genders before casting. This is presumably because of my origin in the Guild and the two main game-writing systems in the Guild, both of which assume variable gender.

LaTeX-quality PDF output and support for variable gender and similar qualities are both features I'd need to be well-supported before I'd consider using something other than GameTeX or Gameki (my own mostly-working homebrew wiki thing).

It's interesting to think that the tools you use influence what game you end up writing. (I guess this should probably get mentioned in my perennially-unfinished post on my opinions on gender at Intercon/in LARP...)
