The latest weekly update has hinted at a couple things being considered to provide content and game balance. Keith, has suggested shrinking the size of the battlescape to force player interaction. He also said Inovea is considering removing one faction and bringing the faction count to two. Then he indicated that Inovae was considering utilizing the rudimentary AI for player balance.
I’d like to suggest a another option.
If AI is going to be used, consider making the third faction ENTIRELY AI driven. This would prohibit the two stronger factions from annihilating the weakest faction. It would also act as a mechanism to SLOW DOWN the strongest faction, by having the AI target it over the weaker faction. This would eliminate the “snowball effect”.
Plus… Inovae could always represent the AI faction as an Alien force…
