Next Generation has published a list of the game industry's 100 most influential women.
It's an interesting list, if somewhat US-centric, with a highly diverse range of companies and positions. One can always quibble with lists like these (as Jason has). I agree with Jason and Kim that Robin Hunicke should have been on there. The same goes for Susan O'Connor and several other kick-ass ladies I can think of.
Nevertheless, I think it can open some eyes. Have a look.
