I am working on Amuni and needless to say have little space so normally I would be looking for some good population building prizes that would let me eliminate some old event buildings and make more room. But right now I am sitting with more than 17k in free population because I have had to eliminate T1, T2 and T3 goods buildings. I just don't need the goods and have no space for them.
And the level 30 workshops produce more than enough supplies for me. Haven't even upgraded all of mine to that level. Just no need.
I wish I had a use for the coin and supplies instants that I keep collecting but again, there just isn't a need. If I visit all the neighbors I have discovered I can collect over 12000 K in coins. More than enough to refill the treasury.
In later chapters progress is controlled by guest race items and sentient goods. Mana and seeds less so. I don't need culture, supplies, population. So unless I see something really great in the prizes I won't be bothering with the event. Of course if thee were more expansions to be earned through exploration, not bought with diamonds, I would be more interested.
