In late December 2025, one game developer toyed with a thought experiment: How much could you tell about a Steam game's success based solely on one screenshot?

It's easy to say not to judge a book by its cover, but the reality is that we're visual creatures. The first thing we'll notice about a game is what it looks like. Strong art direction can be the difference between watching a trailer or closing out of a browser window with total disinterest. Could a screenshot thus be a good predictor of whether a game might find an audience?

A game creator with the handle Newbie Indie Game Dev recently sat down to try and figure out how, exactly, one would go about answering such a question with some rigor. He downloaded one screenshot from every single game on Steam and fed the resulting information to a neural network that would then cluster games together based on what they looked like. The screenshots were automatically pulled specifically from whichever picture was displayed first in the image gallery on that game's Steam page. Presumably, these pictures would be the best shorthand for whatever vibe a publisher wanted to sell for any given game.

From this data set, and in an effort to keep things computationally feasible, Newbie pared the selection down to 10,000 games. He included a screenshot from every game on Valve's platform that had garnered at least 3,000........
