According to data provided by Transfermarkt.com, the most popular and valuable (in terms of total player value) domestic leagues also tend to have the most foreign players.
I was interested in seeing how the commonness of foreign players in domestic leagues has changed over time. To do this I plotted the cities of birth of current and former players as a point on a world map. The larger the point, the more players are from that particular city. There are likely uncaught errors that popped up during the (not especially rigorous) data cleaning process, so I would appreciate any corrections.
According to a research report by Superdata, the PC video game market was worth an incredible $36 billion in 2016. Interestingly, this impressive revenue is mainly driven by “free-to-play” games which generate revenue from optional in-game purchases. While the future of the PC video game industry seems to be invested in free-to-play games, I was interested in exploring the recent past of the industry.
I used data from Steamspy, a website that scrapes data from Steam, the world’s largest digital game distribution platform with over 125 million active users in 2015. Steamspy has data on games released in 2008 or later. After removing games with missing data, the data set has about 11,000 games.
One of the most striking insights that this graph reveals is the overall explosion in the number of available PC games starting from 2013. It’s also interesting that although free-to-play games generated half of PC video game revenue in 2016, only 1.7 percent of games available on Steam were free-to-play. Another thing that stands out is the incredibly fast and substantial emergence of indie games, which grew by 137 percent between 2008 and 2016.
A game’s userscore on Steam is the percentage of its reviews (written by Steam users) that are positive. The trend that stands out the most is that while the first few free-to-play games seem to have been highly rated, their perceived quality has dropped significantly from its peak by 35 percent.
Overall, there isn’t much variability in userscore by genre with most of the average userscores ranging between 70 and 80 percent.
Digital rights management (DRM) encompasses a variety of technologies that are meant to prevent the unauthorized use of digital media. DRM for video games ranges from requiring a CD key for game installation to requiring a constant internet connection while playing the game. The graph shows that the newest games are the most likely to be protected by DRM.
