The "something" in this example is "bag-building", a take on the deck-building game mechanism introduced (and hugely imitated) from Dominion that was first introduced — as far as I know — in Hyperborea, a Chiarvesio and Zizzi design from Yemaia and Asterion Press that I first saw in prototype form in early 2013 at Spielwarenmesse. Over the course of that game players build a bag of cubes that represent different aspects of their kingdom — war, trade, movement, building, knowledge, growth — and they draw a few each turn to activate certain knowledge or technology based on what they draw.
King's Pouch from Keewoong Kim and Korea Boardgames, which debuts at Spiel 2014 in October, does something similar, with players building a bag of citizens, with different colors of citizens able to activate different buildings that they acquire during play. One twist to this dynamic is that citizens come in two shapes, allowing you to somewhat shape what you draw at the end of each round while you're planning what to do next. There's much more to the game, but that's what the video is for:
