Even if it's not available anymore, someone will still read this:

F1 2020 is one of the best F1 games Codemasters ever made. The graphics are good, the sound is good and the handling is pretty comprehensible. 20 Classic cars and F2 cars are included and add to the likeability of this game (historic tracks would have been nice too).
The online experience (in League racing) was pretty good, even tho back then we had to fight with some bugs (which are mostly not even fixed in the current games).
For carrer mode the "My Team" mode got added, which gives you the opportunity to run your own team and extend the grid to 22 cars.

It has some negatives to it too:
The braking is too easy imo. You can smash the brake pedal to 100% in like 8/10 of the cases and would run 100% brake pressure and 50% BB all the time. (small impact)
Unrealisticly spinning out in high speed corners was possible and with aggressive setups even likely. A problem, which has been there since F1 2018 and wasn't solved until F1 2023 (partially). That compromised the useable range of setups quite alot and you kind of had to adjust your driving style to it, what I'm not really able to do. (big impact)
With this game a terrible kind of low speed understeer came into the series and is a problem even in F1 2024. You can't really get around the "Grand Hotel Hairpin" (Loews). (medium impact)
The AI is using it's ERS Overtake button in places no one would and goes for moves too aggressively (medium impact)
Some of the Classic Cars have some unrealistic characteristics, especially regarding pace, top speed/gearing, the F2000 has tc, which the original one didn't had. (small impact)

Overall this is one of the F1 games I enjoy the most.

yes

good
