All right. Last few days I have worked with the story and everything, so here are the answers...
1. Yes, I don't like the name exodus too but Inferno is taken, campaign named "hell" would be funny. What else...the III great war...no, not a chance. So, it will be EXODUS!
2. The Gamma Draconis thing was just a little mistake. See, my Prologue campaign end up with the arrival of sathanas and the juggernaut jumps through a unstabile node. but eight years later, terrans come up with a machine that can open damaged jump nodes. Anyway the make a little visit to Capella. I know, I know PLOT ERROR!!! GTVA just sends a scouting party to investigate. So that's it-no gamma draconis!
3. I know, the plot seems a little predictable but think abou the FS2. When shivans come, it's sure that there will be a battle. When GTVA has Colossus, it's sure that shivans must have something too. But then, Capella explodes and THAT'S a surprise but you people don't know how Exodus ends. THAT'S a surprise too.
WOW, I haven't heard any comments or complains about that 'ground battle' feature!
