Hi Brit -
Just a couple of things, apologies if this has aleady been mentioned. When I restore a saved game it doesn't retain my game speed preference. I've been playing at x5 but after a restore it's set to x1 and it takes me a few seconds of the first turn to realize it's been set back. Nit-picky, I know.
After an upgrade event it seems that all those upgraded units require new orders. I have sentried a couple dozen infantry in my cities for defense and as I upgrade them through the tech levels I have to click each one again to remove them from the 'needs orders' list. Can we have a sentried unit ignored for orders after an upgrade?
Otherwise, having a blast so far with the demo.
