Here's a time-devouring combination of factory-building and incremental game

A cheap little indie released this week combines two notoriously time-sucking genres into one monstrous whole. Widget Inc has the production-matching flow of a factory game but the gameplay of an incremental, letting you build up successive layers of industry in order to make ever more complex technology over 12 tiers of tech and associated upgrades. By cleverly expanding to take advantage of machine adjacency bonuses and terrain types you can get those production numbers ever-higher in order to unlock and research new tech at a good pace.
