I would love to see a grand sci-fi game that's a mixture of Titanfall and mirror's edge.

You would have open world runner sections where your entire job is to run messages between agents on a city/station that is working hard to steer the war... and then you go and do big stompy robots combined arms, titalfall-esque fighting, just open world instead of the (rather great) map, point-to-point of the original.

Alternatively, just give me either a single player or MMO implementation of The Allbright System.

Whatever I choose, I would just like the engine to be released under GPL, and the assets under CC-3.0-BY-NC-SA so that it lives on, regardless of however well it does.
