Stugan is a residency program for indie game designers to hang out together in a beautiful cabin in the Swedish countryside and work on their stuff.
They call it an "accelerator", but don't that word dissuade you. If you consider yourself more of an artist than a businessperson, it's OK, they have hosted plenty of artsy experimental designer types too.
There's been some understandable criticism of Stugan's arrangements: Like many artist residencies and opportunities, there are certain barriers to access -- you're basically foregoing paid work for a few months as a sort of working holiday, and you'll need existing funds to travel to Sweden somehow.
However, I think it's worth noting that many art residencies often have hefty application fees and/or require attendees to pay for their own room and board. Compared to that inaccessible norm in the (messed-up) art world, Stugan is a somewhat reasonable deal that's firmly in the middle of the pack for art, and extremely rare in video games funding.
Of course that doesn't mean it's "accessible" -- so if you're interested in Stugan but don't necessarily have the resources, you might want to do some research into funding sources for artists, you might be surprised. Also, if you're a student, talk to your school -- many institutions offer travel grants for programs like this.
Or just cross that bridge when you come to it? You can apply to Stugan for free. Good luck.
