A Meme. The first half shows a screenshot of the game "Banana" on Steam, showing how it weighs 1.89 Gigabytes. The second half shows a couple of native americans talking on a snowy landscape while inspecting footprints on the snow.
Native A: A western game dev has been here.
Native B: How can you tell?
Native A: It weighs 1.89 Gigabytes.
EDIT: to explain, clicking the banana gives you random "Steam Inventory" items, that players can sell on the marketplace
The entire thing is just money laundry
