That the computer players are not actually players. This I dont mean in such way that the devs shouldnt aim for a great AI. I mean it in a way that the Computer players resemble Alien Empirers, and not computer chess players aiming to win. Alot of people are continuily noting the Devs that the AI could play better in this way, and in that way. For instance, the AI is not raising it's taxes while it could. So it should be made so that they would raise their taxes. However, at this point you are forgetting it's a Computer, who's goal is to win, but also to be the empire that it is.
Let's for one assume there is this really good aligned race which really cares for it's people. That is their background personality. They aim to give their people the best live there is and are not neccesarily aggressive. The race would probably not engage in war and when in war will try to resolve it through diplomatics.
So anyway, this race has a very high morale amongst it people and has their taxes on 40%. Which earns them a medium income. Now they could easily, very easily raise this. Without hurting their morale alot.
So the question is, Should they, for it will make them better?
or shouldnt they? For it is not within their personality to do so?
I believe most people would pick the first answers, and let them increase their taxes, but when doing that. They are no longer race "[insert name]". It would remove personality from races. And even though each race will still have different priorities. They would all accomplish it on the same droid like way. Just trying to be the best. Even though it isnt in their personality.
I do not wish to say that this is a problem right now. As alot of things in the current state of game AI should be changed. I wish to say that all these changes might lead to this problem. I might be wrong though, but I just think it is important that civs have more personality then just a BG story and different priorities of what to accomplish
Just my opinion.
