Or they would compete to see which one can release the biggest amount of shitty DLCs, since Paradox is by no means better than EA.

For a good example of that, look at Europa Universalis IV; the game has, like, 20 DLCs? And the playerbase has been complaining nonstop about the more recent ones; Leviathan for example was the worst reviewed game on Steam, to give you an idea.

Don’t get me wrong, I do think that EA needs some competition here, but Paradox won’t be the ones doing it. (And Paradox needs competition for grand strategy games.)
