The only thing that makes me nervous is the game has so many variables that it can be difficult for humans to decipher. Poor ai and faction traits, planetary bonuses, adjacency bonuses, ideology, ship building, what resources, who is an actual threat, Influence etc.
That said, I think it would be good for the AI to remember the player over games. We KNOW the tendencies of the AI. They don't really know ours. If the player constantly back stabs allies and friends, the AI should remember that over new games. If you are going to be a warmonger with the Terrans, the AI should remember that. If you are going to influence flip them, they should remember that.
I like that Stardock has added some really good game designers and AI guys from other top shelf games. As they say, you combine talent and the talent pushes each other. I was too young to see it, but when I saw a show that talked about the writers on the Sid Caesar Show "Your Show of Shows" I was dumbfounded.
Writers for the series included Mel Brooks, Neil Simon, Danny Simon, Mel Tolkin, Lucille Kallen,Larry Gelbart, Bill Persky, Sam Denoff, Joseph Stein, Michael Stewart, [5]and Carl Reiner who, though a cast member, also worked with the writers.
Just Mel Brooks, Neil Simon and Carl Reiner alone, wow.
No pressure
