Games are expensive. New stuff is expensive. Secondhand stores have existed forever, across all mediums, for that specific reason. Government funded libraries exist for that reason. People should have access to art and media to enrich their lives in our late-capitalist society. Let those who have the resources front the bill first, which then allows for less well-off people to benefit from the secondhand market. This is especially important for games, which are still in the unstable growth stage.
