Artillery seems to work fairly well in that post PA test game SCT provided. SCT is right about the AI's poor handling of siege weapons, but we don't have to give our PA partner any of what we produce. Even if we go the artillery before assembly line, we should still then rush to assembly line thereafter because the infantry really kicks butt when it's up against grens and lbows!

Even does fine against rifles, especially if you give your PA partner CR grens which he then upgrades to infantry

CR infantry
really kicks butts!
Just completed another test game based upon SCT's post PA game. Completed taking all cities on our continent in 64 turns. It works out to one city every 4.5 turns.
The game starts on turn 175.
Turn 191, we got Artillery.
Turn 200, Assembly Line.
Turn 235, Industrialism.
I followed a general North to South progression thinking that if HC's units were near the borders, they would more readily advance on the civ we wanted to conquer (didn't always happen, but not too bad). Some dates:
Turn 183 - Paris taken.
Turn 186 - New York taken, Louis gone.
Turn 197 - Orleans taken
Turn 198 - Washington taken, Washington sent to two islands totaling three tiles between them.

Turn 202 - Hamburg taken and razed.
Turn 207 - Berlin taken, Bismarck gone.
On turn 214, we declared on both Peter and Khan, using a group of infantry and artillery against each.
Turn 216 - Paris retaken from Khan.
Turn 222 - Orleans retaken from Peter.
Turn 223 - Moscow and St. Petersburg taken, Peter gone.
Turn 223 - Beshbalik taken by us and razed (couldn't find HC and got tired of waiting).
Turn 229 - Karakorum taken, Khan gone.
Turn 235 - York taken.
Turn 239 - London taken, Lizzie gone.
A couple of things we may want to think about before we get started. Once there were enough units, I made two stacks of Artillery protected by three Infantry each. I should have had a medic in each stack. This slowed me down, I think, by at least 5 turns. We should have a medic ready to go with each stack.
If we can have some CR2 Maces ready for upgrade to Grenadiers, that would be ideal for CR2 Infantry when we're ready. Also, the more siege units we have to upgrade, the faster things will go.
Another interesting thing was that HC was like a money machine. I went to him twice and asked for half his gold and he gave it with a smile (1000 Gold the first time and 1400 Gold the second

). No need to worry about upgrades with a rich PA.
I used the infantry as well as the Artillery to make sure there was only one weak unit left in the city for HC to easily take. I did have to wait a few times. But he beat me to a city a couple of times.
If we are prepared, I think we can possibly do this faster by 10 to 15 turns. Once Artillery are in play, it moves along. Infantry are also a big bonus, especially when the AI's do not have them!
EDIT - I also built Globe Theater because the War Weariness was getting us down. Better to have Globe and forget about Happiness!
