Wait till you hear about Coffee Stain Studios (Goat Simulator, Satisfactory), Paradox Interactive (I'm not gonna name any games lol, they're literally a genre unto themselves), Iron Gate Studio (Valheim), Ghost Ship Games (Deep Rock Galactic)...
Oh and if you're into mobile games at all, maybe you've heard of Rovio (Angry Birds), Supercell (Clash games) or King (Candy Crush)
And this is all just Nordic countries. There's a lot of stuff coming out of Poland (CD Projekt Red), UK (Rockstar North), France (Ubisoft's been kinda meh the last decade+, but if you only play every 3rd or 4th iteration of Assassin's Creed, they're still kinda fun) and if you consider Iceland to be European which it is, that's where EVE Online is from!
We have a very healthy video game industry, spread across many countries, with many developers with their own unique styles. Indie, AA, AAA. It's lovely.
