So after screwing Harun plans to take Edinburgh I took it, liberated Jakarta, took 2 more cities & wiped Boudicca out, sold her last city to Harun who liberated it & a turn after that asked me to join war against the Celts who had suddenly become a threat to the world - go figure. Renewed my DoF with Indians & the Dutch while seemed to have a sudden interest of my borderline which was very long since we cleared the Celts side by side he takin coastal & me inland cities. As a self preservation measure I took DoF with Harun, too and we were all part of a happy quartet. Rammy was not too happy, Isabella turned guarded after I declined her engagement offer while I couldn't care less about Sully's opinion since he was excelling himself in industrial espionage on my account.
I was happily cruising towards goal & building Apollo & Manhattan when Harun backstabbed @T215 so the money saved for Space ship factories was invested in bombers. Harun's army was quite impressive since he had more rocket artillery than there were aluminium around. First unit I killed was lacking resorce but not the rest so I lost a unit or two per turn. Since I had no trading partners I sold sci buildings to get money for nukes. Didn't much delay my research but I used faith for GSs instead of GEs which was original plan. Obviously inspired by this clash of will William denounced me out of the blue after taking Freedom in contradiction to my Order. I was clearly right but he didn't care.
Harun's 3 closest CSs allies were deep in my land the turn war started while mine were playing with themselves - the slackers couldn't care less about Harun even though they shared 8 tile border with him. After first nuke which I couldn't target a city because of a totally lost Siamese prophet Harun's interest focused on my CS ally which fell in two turns. Meanwhile the co-venture of his CS ally trio took one my puuppets so lost 8 alu, not a catastrophy but an unwelcomed event nevertheless. After that I soon lost another puppet and another alu stack while still beeing safe or so I though. 2 turns later I was suddenly with -2 alu without any reasonable explanation so I had to GG bomb the 8 stack back to continue building parts which was struggling anyway. Only Palenque with SSFact & another city without one building parts while others were building tanks. Nukes were bought as soon as wallet permitted.
15 turns of warmhearted nuke exchange in which he lost quite a few bombers and a city while I lost all my 5 bombers I finally had the parts - Harun had 3 or 4 but enough votes for Diplo vc in first vote. Extremely slow part building process but certainly much more livelier end than usually. On the other hand I somewhat lost interest soon after Harun DoWed so I just did just enough to win.
While I appreciate Harun's effort to save the game I don't like CS behaviour nor the other illogical happenings. The aluminium tile I bombed back to myself belonged originally to a city I had all the time but apparently swapped during the capture which shouldn't be possible.
If I'd do it again I'd build a slightly bigger army to actually do some coquering early on. Now my initial army was just to catch Ottoman workers. Boudicca was about DoW me around ~T100 but somehow decided against it or was scared by Gandhi DoWing while she was setting troops on my border. Even more odd was that her troops never left but stayed there hovering around until border expansion pushed them away.
A serious mistake I made was too slow expansion in the beginning but I was slightly confused by the Ottoman early settlement - I expected troops as well so I didn't build settler early enough. When I finally did I had to buy libraries instead granaries so the initial growth was tiny. The starting location just was too good so anything goes.
Not a hard game at all possibly apart from the last 20 turns but it'd have been extremely easy if Harun had been a regular AI moron instead of a superpower. He took Spain practically before I met either of them and crabbed a bit Boudicca while his cities were growing like no end. With his gpt & full patronage others getting a CS ally was a rarity.
A pure warmonger approach would be interesting and sub T200 domination very possible. Apart from Harun the others were seriously behind in tech from T100 though most of them went for military techs.
