Just seen F1 2020 in the Stadia store. I didn't see any announcement about it, but I guess if you like racing sims and didn't know about it I think it came out on July 6th.
I can only see the Deluxe Schumacher edition available for purchase and not the base game - I can click on the base game but no option to purchase...not sure if this is the same for everyone?
The base game is going for sale this Friday.
Bought the Deluxe edition which runs pretty good. Got some problems using the only servers of Codemasters.... And some loading times are a bit long.
