I appreciate all the replies! Really.
@Beetle I would say I am fairly good at Deity. Really it's the manipulating that gets me on top. The times I lose on Deity is if I am next to 3 aggressive Civs it seems like. Also, if I play Deity on anything other than Continents or Pangea, I get in trouble because in higher levels if you let certain Civs sit, it can get out of hand.
Civs like: India, Ethopia, Siam--you don't want them not being pushed. And being isolated doesn't help me.
When I play on Deity and Immortal, I am heavily focused on military. I rarely have time to plan how I want to win a game because my mindset is on: defend, defend, defend, then attack.
The only time I actually won how I planned it, was with India and Venice. Because they don't require much responsibility and their areas are tougher to take with them not having multiple cities.
And with the Ancient and Classical wonders you mind as well forget it. I recently played a game as Japan and I was shocked when I pulled off getting the Hanging Gardens. But I did have a great start location.
But out of nowhere the Zulu and Huns DW'd me and I'm like WTF. They had a carpet of units. I had a decent army but the GPT suffered. Nobody and I mean nobody wanted to be my friend after I ended the Danish. But if I didn't do something about the Danish they would've gotten me first I am sure of it.
So I couldn't make any trades. Empire was Unhappy. I even tried to sell a luxury to a civ with -10 GPT and they STILL denied me. So it's like, if you want to be aggressive early (which you'll need to), you won't make many trading partners.
The games on Emperor get so peaceful that I purposefully put aggressive civs in the game just to shake things up.
But it's like noto2 said
You will fight centuries fighting these Civs and so many Hammers are used on units you won't be able to develop your cities beyond what your Workers will do. But while you are constantly fighting they are Wonder spamming and before you know it your Longswordsman is fighting a carpet of Musketmen.
But let's say you make peace? What next? Ohh that's right, you have to play catchup. Because the AI already started off with: 2 Workers, 2 Warriors, 1 Scout and a plethora of other bonuses, not to mention the free techs.
I haven't gotten the mod yet.. What I did do is use the IGE to set myself 2 Workers, 2 Warriors, and a Scout, and the free tech. I played as Ethiopia. And yes, the game is difficult but still fun. Danish were located on the SW side of me. Shaka was in the north.
He DW'd Bluetooth. Shaka drug his units (and Impi) ALLL the way from the north squeezing through the borders of Rome and Brussels, trucking through the Jungles, and Bluetooth let him take every city he had except the capital.
I was like, how the hell you let him do that!? If it were me, they wouldn't even have made it past the Jungle.
I will try the mod when I get the chance.
I mean, it's not like Immortal and Deity is impossible, but I think there should be an option between: having a game where the AI gets insane bonuses, or a game where everyone is even but the AI is more challenging. They have an option to randomize leader personalities, so why not?
