Currently three other Kixeye games of this genre exsit:

In War Commander, you are the leader of an army attempting to seize power by crushing opposing forces and dominating the landscape.

Battle Pirates, a game similar to VEGA Conflict, places you in charge of a fleet of pirate warships in a post-apocalyptic world covered almost entirely in water.  You are a captian in the Forsaken, a group of pirates fighting against the Draconians who control the world with an iron fist.  Of the three games listed here, this game is almost identical to VEGA Conflict in gameplay, and therefore is a logical choice for those who wish to try other games by Kixeye.  

In Backyard Monsters, you command a group of various creatures with the goal of dominating rival factions and defeating other foes.
