Of course I knew about CD Projekt Red and Paradox. Somehow the titles I mentioned caught me by surprise.
About France, you could have named Arkane. They did Dishonored which was really really good.
Only Italy does not seem to have a gaming industry to speak of.
On mobile, why would I play Angy Birds when I can play Dead Cells (free right now in the Epic Store for Android, though it's well worth paying for)? Though I have to admit I'm kinda addicted to the open source goodness of Shattered Pixel Dungeon and Mindustry. Likely not made in Europe, but so good, and you can get then straight from F-Droid.
Damn that's cool.
