If you want to spoil other games that straddle the imagined psychogeography of the casual/hardcore divide forever, the Rebuild series [official site] is a good place to look. On the surface, these strategic games of zombie uprising aftermath survival and urban reclamation are simple, colourful resource-gathering exercises, but they’re cleverly balanced and squeeze plenty of flavour out of the setting. Since the earliest Flash incarnation of the concept, Sarah Northway’s games have appealed to me – ideal to dip into during the eternal coffee break of the soul.
The third title adds factions, a splendid revamped UI and much more. I’ve played the early versions of the Early Access release but now, with the campaign complete, the game is ready to launch.
