Homo economicus
Molleindustria named "Diamond Trust of London" as one of their top games of 2012, describing it as Rohrer's "most elegantly designed game to date". They highlighted how it critiques the blood diamond trade by using game mechanics that present "the world from the cynical, detached perspective of the Homo economicus", rather than by lecturing the player. "Paste" echoed these thoughts, stating that the game offered "no overt judgments" on the diamond trade, but had mechanics that paint it as "one that encourages and maybe even requires misdeeds". Reflecting on the game's unlikely journey in becoming a physical product, "Paste" declared "Diamond Trust of London" to be "not just a success in design, but also one of creation".
