Ug. Developer find easy way to get shiny rocks with little work. Many caveman play game to get rare skins to trade at Steam market. But skins almost always worth tiny bit, like 0.03 shiny rocks.

Then, caveman trade skins. Developer get 0.01 shiny rock, Steam get 0.01 shiny rock, caveman get 0.01 shiny rock. Caveman do all work, get almost nothing. Developer get 0.01 shiny rock every trade!

Game just click on banana picture, not real game.

For example: Game give skin every 3 moons. Skin worth 0.03 shiny rocks. If caveman get 8 skins in sun, that 0.03 * 8 = 0.24 shiny rocks. Minus Steam and developer take, 0.08 shiny rocks, caveman have 0.08 shiny rocks left.

Many caveman play. Now 42,000 caveman. Developer make big shiny rocks every sun: 0.08 * 42000 = 3360 shiny rocks!

Developer get rich easy. Not fair to caveman. Numbers not exact, but truth same.
