something I would like to see implemented in this game is roaming AI controlled armies that can attack player controlled cities (and possibly even retake wonders?).
I think it would add a fun element to the game, especially if an extremely large AI army were to spawn and begin attacking players in the middle of a war between two large alliances, it would really help spice things up a bit.
It reminds me of sim city when a tornado would spawn. It sucks if it hits you, but it's fun to watch regardless.
Could also build on this where the AI army would be led by a hero, and if a player manages to successfully defeat the AI army, he / she could get an approval card of the hero who was leading that army.
Again, this is just a suggestion, something I thought up in 5 mins while the servers are down. I would love to hear other players views on this, and any ideas they could come up with to build on the idea. Thanks.
