I don't know about easy, BUT you can get addicted to anything. If you really like something, and it triggers those endorphins in your brain, and VR just might, then sure you can get addicted. But probably as you said it's the games and gaming that is the bigger addiction. Like those addicted to first person shooters for example or World of Warcraft and other MMORPG games.
Used with care in limited doses for entertainment purposes and you should be fine. IF you notice yourself having a problem, then maybe it's time to put it down for a while, and if you can't then seek out professional help.
