Wait for FIFA 20 Reviews
If you want to really know what you are getting into for $60 to $100, you should wait for the FIFA 20 reviews.
You can expect to start seeing FIFA 20 reviews in mid September as the EA Access and Origin Access release is likely on the 19th, and that will bring about not only reviews from critics, but also from regular players.
This is where you can learn about how the FIFA 20 gameplay changes actually feel in the game and if they deliver on the promises.
Reviews can also help you understand if the new Volta mode delivers a fun experience, if there are any issues with online gaming and how grindy FUT is in FIFA 20.
