The top 10 free-to-play PC games that are best at separating players from their money

The government may spend a close to $9 million on every M1 Abrams tank it buys. Gamers in World of Tanks can sorta relate.

The online multiplayer game, which has teams of players in tanks fighting against one another, has the highest average revenue per user (ARPU) out of any free-to-play PC games, according to a report form industry intelligence firm SuperData Research. Of course, World of Tanks fans aren’t dropping millions on their digital vehicles. Instead, the average player spends $4.51. That puts it ahead of games like online shooter Team Fortress 2 and online strategy game Dota 2 — at least in this one metric. ARPU is an important factor in the multibillion dollar F2P game industry. It measures the health of a game that relies on microtransactions, but it doesn’t tell the full story. For example, games with more players and a lower ARPU can still bring in more money, which is how League of Legends (ARPU $1.32) generates more revenue than its competitor Dota 2 (ARPU $1.54).
