Alphabet's Google recently did some research into what teenagers think is cool and, perhaps unsurprisingly, it found that teens have a very high interest in video games. In fact, no other hobby was more popular with teenage boys. Meanwhile, the average age of video game players is 35, according to the Entertainment Software Association, which indicates that gaming remains popular long beyond the adolescent years. So series that are popular with teens now could have strong staying power and growth potential.

Generation Z began arriving on the scene in the mid-1990s and Google focused its research on those aged 13-17. "Video games were on top of the coolness scale for boys," the company wrote. "They think video games are cool not only for their storylines, wide variety, and ability to escape to a virtual reality, but also for the ability to connect with friends." 

Click through the following slideshow to see which series from Activision Blizzard (NASDAQ:ATVI), Nintendo (NASDAQOTH:NTDOY), Microsoft (NASDAQ:MSFT)Take-Two Interactive (NASDAQ:TTWO), and Valve Corporation took spots on this list of teenagers' six favorite video game franchises.
