The idea that art flourishes under capitalism is mind boggling to me. There's literally a stereotype of the Starving Artist who can't make any money off their art because art is incompatible with capitalism. Whether it be the traditional perception of art as paintings, or novels, or other creative mediums such as video games. Right now, due to the profit motive, game companies churn out sequel after sequel, rehashing old concepts ad nauseum in order to keep making $$$ off of what they know works instead of trying new things.
Looking on the other end at the indie and hobby sphere of game dev, we get some amazingly creative ideas. Games like Cave Story, Fez, World of Goo, and Undertale exist because developers wanted to make something they thought was cool. Many indie games are made as passion projects while the developers work day jobs to put food on the table. The games weren't made for profit, they were made because the developer was passionate. In other words, they were made independently of the profit motive.
Sure, maybe a great many indie developers dream of hitting it big with their games, but almost always that's because they want to be able to dedicate all their time to the art they are passionate about, and they want their art to be shared with others and enjoyed.
If not for the fact that making money is an unfortunate necessity in a market-oriented society in order to put food on the table and have a place to live, we would see so many more passion projects resulting in amazing new experiences. Video games would thrive so much more in a moneyless society.
And as a preemptive: I know if I got more into arguing about this and arguing for a society where food and housing are freely available (edit: e.g. in a moneyless society), somebody would surely ask "well then who would grow the food for free and build the houses for free?" This is super anecdotal, but I already am growing my own garden, and I'm trying to expand it enough that I can begin giving out extras to people in need. If I had the opportunity to work on a big enough farm to provide food to everybody else, you can bet that I would jump on that opportunity. And with how many people are on the planet, it is statistically improbable that there aren't many others out there who would love to do the same. With a shift in cultural mindset, I bet many more people would be happy to contribute as well.
