Along with the new version of NRG scheduled to be release at the end of this summer a series of MicroGames have been added to the learning section. Theses MicroGames consists of quick sessions (7 to 10 min. each) that show you step by step how to implement a base framework for a specific type of game.

Below find a few screenshots from some of the sessions (in no particular order):
