I have been a gamer girl since the mid 80s. I've played in female-heavy and male-heavy groups, but my favorites have a good mix of both genders. My normal experience has been about 2 or 3 girls to about 3 or 4 guys. However, I tend to be the only girl that GM's.
Currently, I am running RotRL and absolutely loving it! The players are having a blast as well, from what I can tell. The party consists of:
1) Jacamo, a male Varisian sorcerer of fire-elemental bloodline, played by my husband. He and I have been active gamers since we met back in the early 90s. He's a lot more into other games than I am, though. I tend to stick to D&D.
2) Eoletta, a female Varisian priestess of Desna, twin sister Jacamo, played by my younger sister. She's just getting back into gaming, having not played since 2nd ed.
3) Xandu, a male Varisian fighter, played by a male friend. He started gaming when 3rd ed came out, then dropped out for about 4 years, and then started back in about 2 years ago.
4) Rico, a male Chelaxian rogue, played by a male friend who is also just starting to get back into gaming.
5) Amasali, a female half-elf ranger, played by a female friend and co-worker who has never gamed before in her life. Incidentally, she is the most eager to get us together to play! Yay!
I haven't been so excited about running a game in a long time. When I read Burnt Offerings, I couldn't wait to get some people together and run it. And with all of the dramatic role-playing opportunities presented, I knew I'd want a good mix of male and female players.
