Something to note: Bushiroad's international marketing strategy is different than it's Japanese one. In Japan, this game is marketed towards kids, but here it's marketed towards TCG players, particularly Magic players, just like CFV was marketed towards teens in Japan, but bored yugioh players here.

So, most players outside of Japan are probably going to be older, not that kids won't be playing this.
