I actually looked into this, part of the explanation is that in the 80s, Sweden entered a public/private partnership to subsidize the purchase of home computers, which otherwise would have been prohibitively expensive. This helped create a relatively wide local consumer base for software entertainment as well as have a jump start on computer literacy and software development.
This is the real explanation. Couple that with a push in the late 90s/early 2000s to roll out high-speed unmetered internet in the form of ADSL and later fiber.
Finland also has a disproportionate amount of highly successful games compared to the population. I guess one theory is that good social safety nets make it more feasible for people to take a risk starting an indie game studio that might not yield any money for years instead of working for a big corporation for a guaranteed paycheck.
Quebec also has a disproportionate amount of successful games for similar circumstances. Video game salaries are pretty well subsidized (although it was originally only meant to encourage Ubisoft to open a studio then other companies joined or got created so they kept it). The current government is threatening that though.
That's on top of socialized healthcare, low electricity cost, and the Canadian Media Fund but those all apply to the rest of Canada as well.
Quick list on top of my head:
Indies: Outlast, Dead by Daylight, The Messenger, Spiritfarer, Ultimate Chicken Horse, Fez...
AAA: Deus Ex, R6 Siege, For Honor, some of the better Assassin's Creed and Farcry, Batman Arkham Origins
Valheim and Satisfactory are masterclass. GOAT simulator is good for 6 year olds. Raft was kind of dull be entertaining with multiplayer. V Rising I didn’t really care for, but haven’t played since it was first available on Steam
I bought it the very day it came out for no real reason and fell in love with it. Put about 500 hours in it before any updates happened. Played a little since then but those higher tier biomes are pretty brutal. Gonna wait until it’s 1.0 before jumping in again. Best $20 ever
While I disagree with how long they're been in early access especially when other games are in early access and doing it better... The updates were still pretty impressive. The new biomes were pretty interesting.
It’s been a while but I remember I was annoyed with something to do with having to find blood. I know that’s really stupid considering it’s a vampire game. Also the top down view i have a hard time with these days since I played so much Diablo 1+2 back in the day
My first ever international business trip (in the late 90s) was to Skovde, and that was for software development reasons. So the town has a long history for it.
I honestly thought it was just an asset flip that turned out to be kind of funny and so was tolerated I didn't realize that it was made by the same people that made Satisfactory.
It's all you said, but it's also a product of it's time. Iirc when it release there was an increasing amount of simulator games, and goat simulator pokes fun to all of those while having tons of silly references to the contemporary things.
The successors don't have much of s point to me tbh.
the point of goat simulator was that it was a three-week goof project the Sanctum devs had fun with to celebrate good sales before they got to work on the sequel.
