Nexus:jupiter incident was a great game, I had a pledge for the last kickstarter for nexus2 but that didn't reach the goal. Pledged again for this.
For those that don't quite get what this is about, it's basically space war but focused on the tactical aspects of it. I don't know about nexus 2, but nexus 1 was basically a storyline of connected encounters/battles and there was no basebuilding but you did get to manage resources that shaped the fleet you controlled.
It is basically a bit like homeworld but without the capital ships as production centers.
For those that enjoyed the Crest of the Stars / Banner of the Stars 1 anime, this is also a must buy because I think it captures well the "feeling" in that show. They are completely unrelated, of course, speaking only about the "feel".
