In this GDC 2012 talk, Grey Area's Markus Montola discusses Shadow Cities, the first location-based MMORPG in the world, and some of the key lessons from the early days of mobile location-driven video games.

Montola goes over a few points including how using the real world to guide level design made the game inherently unfair, and the difficulty of finding new solutions for game design tactics that were no longer applicable.

It was an insightful talk that's definitely still worth watching, so developers shouldn't miss the opportunity to do so now that it's freely available on the official GDC YouTube channel!
