1. Create the directory /home/deck/Games/ea/pfx. This will be the Proton prefix and will make it easier to get to when things invariably go wrong at some point in the future.
2. Download the EA app
3. Add non-Steam game and find the exe
4. Edit the app's settings in Steam
5. Rename the app to "EA App" for cleanliness
6. Nuke the contents of "Start In"
7. Set the launch options to STEAM_COMPAT_DATA_PATH="/home/deck/Games/ea/pfx" %command%. Feel free to add other options like RADV_PERFTEST=gpl.
8. Flip over to Compatibility and force a version of Proton known to work. 8.0-2 was used when writing this, but I will forget to keep this up to date, you should do some research.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.
