A while back were were supposed to get ideology from invasions, instead they made it a trait. I think we should have more options on how to get ideology. Since we interact with the map ONLY for colonizing or invading we need to derive them from those sources. I daresay trade would be good but we only really have a handful of trade routes per game, although those would also be a good source.
In addition to those, Espionage can and will open up possibilities to get ideology points.
Personally what I would like to see are more moral or thought provoking choices where the options presented are all good or all come with consequences if you chose another.
As an example:
We are given a choice upon Colonizing of several events that we can have happen. Most do not come with a malus and playing with a malus is bad design. Instead lets play with "Sure you can make slaves of the population now for +10 raw production or if you integrate them your chances of unlocking a secret tech tree go up by 20%". Notice that both are good choices and one is an unknown.
What secret tech tree you say? Why the one that is there to all players if they can unlock it! There are actually 3 trees that are secret (weapons & defenses, Diplomacy and trade, and finally population and production), This also forces us as players to make choices that can and will 'drag out the game' well into and past the Ascension era..
Sorry Seilore, I had a thought and ran with it.
