Adding vs cutting features

A friend of mine, currently employed at Mojang (the people behind Minecraft), did a nice blog post about adding versus cutting features in games. As a developer I know how tempting it is to add cool features, but it's damn hard to not lose yourself and your game in a frenzy of cool but often unnecessary stuff. I could use a punch in the face now and then since I often find myself side tracked in Dweller. I need to improve game play in Dweller, not refactor the UI for the nth time or spend time coding cool technical framework features that has no impact on the game itself.
