My number one complaint about 1UPT... Drumroll please... When you are defending a city and you have a unit (usually a ranged unit) garrisoned in the city... You CANNOT send another unit through the city to attack an enemy in an adjacent tile. I just had a war that was waged over a city I built on a narrow isle so that I would be able to send naval units through and have a more direct route through the continent. So anyways, the AI had 2 land tiles on his side of the city. I had 1 land tile on my side with a catapult garrisoned in the city. Well, he would line up his units on both tiles on his side. I had all of my knights and longswordsman eagerly awaiting to attack his units but they couldn't because I had a catapult garrisoned in my city and no other land route around to the other side! Soooo frustrating. Another frustrating thing is I've had a frigate and a cannon both in a city at once, but the unit icons where stacked ontop of each other. When I clicked the icons, only the cannon icon would come up because that was the one that was ontop. Nothing I did could access the frigate and I couldn't just move the cannon because my city was under seige and I need to bombard the enemy units! This REALLY frustrated me as I had no way to access the unit. IIRC, in every previous civ you could access all of the units garrisoned in there by simply going to the city view screen. But what do I know?
