Sometimes a single idea elevates an entire design. Take Fabio Lopiano’s Merv: The Heart of the Silk Road, for instance. Viewed from a distance, it might look like a boilerplate modern euro design, crammed full of bells, whistles, and intersecting means of accumulating points. It isn’t until you dig into its heart that the truth becomes apparent. It’s still a boilerplate modern euro crammed with bells and whistles. But it’s a boilerplate modern euro with one heck of an action selection system.
