No, the PC videogame market is too small for the European Union to analyse it.
If the local hardware store is the only one selling screws for 100km around and it doesn’t show up on their list, does it means they don’t have a monopoly or it simply means that they don’t bother checking that because the hardware store doesn’t:
Make 6.5B a year/doesn’t have a market capitalization of 65B
Doesn’t have 45m monthly users in the union AND 10k business users in the union
Meets those criterias three years in a row
Because these are the criterias required for the EU to take the time to analyze a companies’ position in their market.
