The organisation game representing most of the companies present in the german gaming market has released a report about the revenue in 2020. The report is in german though.
The main data is condensed into this graph:
From top to bottom the colored segments on the graph are:
- fees for online services
- purchases (I assume the actual game purchases)
- in-game purchases
- hardware (consoles, handhelds, gaming pc, accessories)
The numbers are in million € (the european currency).
