While there is no doubt that there mobile card games are here to stay, it should be noted that card games have existed since decades ago, beginning with the likes of Pokemon, Magic the Gathering and Yu-Gi-Oh!. The only difference is probably that the games are free and easily accessible. Even without those factors, games play Pokemon and Magic the Gathering have survived even till today. This is definitely something to take note of. It could mean that this is not the ‘creation’ of a trend, rather than a technological advancement that made a popular trend even more popular. This, of course, is pure speculation.
