FFXV even says as you boot it up "It's for fans & new comers". I'm gonna tell you YES. I am a fan of FF but not a super hardcore fan. I am really digging it. I at around 20 hours in, level 23 characters. I'm loving it so much I set my alarm for 4am-5am so I can get in a good 4-5 hours before I have to goto work. I would wait til after work, but I put 6-8 miles on my feet during my work day so I'm simply too tired to play after work.
So "YES", definitely play it. If you're apprehensive, GameFly is a wonderful service. I've been with them since 2007. At least you could give it a try by renting it. Then choose to buy after some gameplay.
