Chinese gamers tired of playing games online by themselves can now pay between 20-100 yuan (US$3.20-$16) an hour for a female online "escort" to play with them.
More advanced services offer a female gamecaster who will explain and demonstrate games to the players via face-to-face online chat.
"If a woman has a sweet voice, this will be even more popular than any gaming skills she might have," one escort brokerage firm said.
He said that those seeking female "escorts" are usually white-collar workers living in coastal areas who are willing to spend money on online games.
A lot of female college students and office ladies moonlight as these female "escorts" for online gamers as a source of income. Supply and demand are equally hot, the firm said.
"It is common for an experienced female escort to make 3,000 yuan (US$485) a month," one firm said, reports Want China Times.
Top female "escorts" can make up to 8,000 yuan (US$1,300) per month, and the commissions paid to the firm are usually between 5% and 10%.
In addition to honing the skills of online players, the women who serve as gamecasters see it as a money-making venture.
One Hong Kong media outlet stated that the trade in "gamecasters" has been going on for some time, with some women who have won online game competitions able to command annual salaries that could start at 10 million yuan (US$1.6 million).
The brokerage firms say the market potential for female "escorts" and gamecasters is big, but added that a lack of effective regulation often leads to disputes or even fraud.
Some players are quite blunt in saying that they want to see their female "escorts" offline for sex, which leads to the question of whether this line of work is merely another front for prostitution.
