A 2011 study showed that females made up 47% of the gamers, up from 42% in 2010. females are (according to a bunch of studies) the fastest growing segment of the market and, apparently, the growth is in online, social games such as Second Life and Fantasy RPGs (although not ones with gloomy depressing scenery)
Other studies show they gravitate to games like The Sims, or games where they can build/make things.
Apparently, in 2013, the percentage of females playing MMORPGs is approaching 50% in total.
Do people fell like its true in LOTRO?
Maybe Sapience might share some rough ideas with us.
BTW, my grand daughter asked me (she is now playing LOTRO).
