Question

what is the cheapest game on steam

Answer 1

Steam frequently has sales and allows developers to set their own prices, so the title of the cheapest game can change often. However, as of my last knowledge update, games like "Doki Doki Literature Club" and various other indie titles can be found for very low prices, sometimes even as low as a few cents or free. Additionally, some developers offer games for extremely low prices as a marketing strategy.

For the most accurate and up-to-date information, I recommend checking the Steam store directly and sorting games by price.
