What do you think of Steam Direct?

Fact checking time.

Amnesia wasn’t Frictional’s first game - they were an established studio with three titles behind them at the time of releasing Amnesia: The Dark Descent. Their previous three titles (the Penumbra series - stylistically similar and in the same genre) were published by Paradox. To say that the game couldn’t have been made under a studio/publisher model is quite erroneous given that it’s three predecessors were. Frictional however had the ability to self publish for their fourth title; so they did exactly that.

Torchlight was an investor backed team of veterans, and ultimately was published by Perfect World. Stardew Valley was published by Chucklefish.

The Ship is exceptional in that it is a mod that later saw a standalone release as a game. Factorio was crowdfunded through indiegogo and through it’s revenue from essentially being ‘early access’ for a few years.

Numerous publishers exist for these kinds of games. More importantly, all of these examples had the capacity to spend $5000+ on the proposed Steam entry fee.
