Suggestion for EA play: Cross platform Gaming/Support
Keep in mind EA may change the price with this suggestion how they see fit.
Much like EA's Cloud system to save settings; a syncronisation hub for EA play and game purchases/game library.
To ensure security:
Two factor authentication on login is a must when using EA content with EA play, not only does this prevent illegal copies but also protects the user account from bans or rule breaking.
Behind the scenes the account could also be regional/country locked to add extra security. (country of which you logged in not blocking cross country online play)
This will allow users to have EA play status across linked platforms and share games/library between them when synced.
If a user were to change platforms from console to PC or vice versa then they can simply setup their EA account on that platform, download their already purchased game from the previous platform and Play.
This would make EA titles more accessible without having to think about the costs. (because your already subscribed to EA Play.)
