I love this game. It absolutely harkens back to my own time as a tabletop gamer, with both D&D and CCGs, and its story treats those memories like they're a treasure, rather than a punchline. Will you enjoy it as much if you don't have those memories to draw on? Well, if you like fun, and can stomach learning something new, then I don't see how you get out of this without having at least a little. It may not grab everyone the way it has me, but then it doesn't have to for you to see its charm. And hell, it's.. mostly free. So you have no excuse.
