People who spend money on digital collectible-card games spend a lot on them

One thing all free-to-play games need is an item or resource that people will want to repeatedly pay money for, and digital card games have found that in their booster packs.

The people who spend money on digital card games spend around $90 per year, according to the gamer-polling company RapidPolls. If you include people who never spend any money, that average drops to a respectable $38.53. This shows the health and potential of this segment of free-to-play games. Digital card games like Hearthstone and Solforge have turned the card-based gaming market into a $1.2 billion business worldwide in 2014, and that’s expected to grow to $1.3 billion by the end of this year.
