Not indie but still good:

• Remedy - Control, Alan Wake.
• Embark - Finals, Ark Raiders.
• Flying Wild hog - Trek to Yomi

Kingdom Come Deliverance 1 and 2 by Warhorse Studios - Czech

No Man’s Sky by Hello Games - UK

Planet Coaster 1 and 2 and Planet Zoo by Frontier Development - UK

Don’t know if it qualifies as an indie game but Clair Obscur Expedition 33.

Lead dev of Ultrakill is Finnish and he said it’s okay to pirate the game if you can’t afford it

There are so many! What kind of games do you like? For example Spilled! Was made by a Dutch solo dev while living on her houseboat.

Valheim, with couple of friends it is one of the best games in decade. Done by swedish team iron gate and published by coffee stain which is also swedish.

I’m biased because I go to the same school these guys went to but check out Wrong Organ: https://www.wrongorgan.com/

They made Mouthwashing and How Fish is Made, both are weird as fuck
