Just played possibly the worst game ever and after that I'm done with Deity. It has completely ruined the fun of this game for me.
Around turn 125 everything is going fine. I had taken Istanbul with some crossbows and was nicely working towards public schooling with 6 cities ( 2 were Ohttoman).
All of the sudden Celts conquer India and the very next turn I get a DoW from The Celts and Harun at the same time, and from that point on there was no making peace. I hadn't done anything to piss either of them off, and my military Strength was not far behind and I was equal or ahead Tech wise. At one point neither one would even take 2k gold + gold + cotton + 30 gpt. This turned into a million years war. At this point almost every turn I was trying to get the Dutch to go to war with either of them and he wouldn't do it even for all my gold, plus gold and cotton, plus Istanbul! So as Harun starts marching into Istanbul, I sell it to the Dutch for everything he's got and we sign a RA as well. After about 50 turns of easily fighting off the Celts in the north while Harun is finishing off Spain, all of the Sudden Mr. Dutch that won't go to war with anyone decides to join in on the virtual gang bang going on in my territory. This was around turn 175 or so. Maybe less.
At this point happiness is a problem, almost dipping into double digits because Harun has swallowed up every City State.
This lead to a few things happening that made me realize how horrible Deity is.
1) The Computer can Ignore Unit Movement restrictions when moving by/around hostile units. Which is absolute .
2) An Infantry (The actually infantry unit not the class of Infantry) inside a Great Citadel can literally hold off any attack by the most powerful/leading computer player indefinitely, not to mention watching him kill 6, yes 6, enemy war bombers single handedly in one turn. The A.I. is horrible.
3) The computer does not give two shits about the other computers. As Harun begins building space parts, The Celts and the Dutch couldn't give two shits in the world about stopping him. The entire game the Celts and Harun and the Dutch never went to war once. And believe me I attempted many times to bribe them into it. Even before they DoW me.
4) The Computer can coordinate an attack with their C.S. Allies, basically tripling their attacking Strength, which is once again absolute .
It's pretty clear that Deity is a game of Patterns and every game is follow the same pattern, until just gets irrational.
Edit: It is just extremely frustrating, because after the double DoW there was literally nothing I could do. I had out teched the Celts and beat everyone to bombers and then infantry, but I couldn't push into anything because of the pincer that is created by the starting point. The game shouldn't be over at turn 125 but it was, because The Dutch wouldn't fight anyone, and the Celts and Arabia wouldn't make peace for anything.
