Mike Rose writes: "I analysed Steam sales data from the last month, and found that:
• The average game is selling around 1,500 units, and making around $16,000, in its first year on sale
• That's down 47% year-over-year
Note that this is based on analyzing only the top 20% of games -- I removed the bottom 80%, as that 80% are barely making any money at all.
If I had included all games released on Steam, these numbers would have been waaay more terrifying."
