I've been working on OpenNERO this semester, along with Igor Karpov (lead dev), Adam Dziuk, Leif Johnson, and Risto Miikkulainen.
The idea of this tournament is that you are training a population of evolving agents, each controlled by a separate artificial neural network. It's effectively a strategy game where you teach your networks how to react to different inputs (flags, enemies, friends, etc.).
We'll then compete the teams against each other in a massive tournament.
