I heard a lot of changes have been made related to iron golem farms. There's an atmosphere of pessimism around iron golem farms after 1.2.2. I'm gonna follow this tutorial on creating an iron golem farm. The title says it is compatible with 1.3.2 but I'm not that sure.
What has really changed during the history of minecraft regarding iron and iron golems? Can we still properly farm iron golems? Is it worth it?
