There isn't much of a market for virtual reality games at the moment, but Ubisoft thinks it can help create one. Company chief Yves Guillemot tells investors that Ubi is developing a "certain number" of titles that will take advantage of VR devices once they start reaching stores in 2016. He's not specific about which franchises will get the treatment, but he says that the company is "very bullish about the potential." Supposedly, VR will lead to more immersive gameplay that could "bring more players" to gaming. The big challenge, according to Guillemot, is building games that suit the virtual environment -- it's hard to play a long time with a display strapped to your head.
