I was wondering, is there a reason why there is often a rush in Deity at the start ?
No, you're not. If all you want to do is defend, then 2 Melee Units and 3 Archers are already enough for that. Fortify the Melee Units, use the Archers to kill units until the AI offers you a peace treaty that will likely have a large amount of gpt attached to it.The real problem with immortal and deity is that you are forced to sink so many early resources into an early army to defend yourself from the inevitable AI rushes, that you are basically forced to go on the offensive with it. This makes pursuing peaceful strategies hard.
You say this, but in one of my first games, Gandhi and Scythia teamed up against me around turn 25. Scythia eventually accepted peace, Gandhi was fanatical and wouldn't accept any peace terms at all.Warmonger penalties... war weariness... oh the humanity...
generally you should only war to get your core up (if the AI takes the space you want or the AI comes for you anyway, which they will)... mid to late game wars are more trouble than they're worth for sure. The AI don't develop their cities mid-to-late game as well as a human player would, and their growth is still crap.
If you spawn next to Gandhi, sure a completely peaceful victory is possible... but other than that expect to be hit and having to defend with archers.
Has anyone had any success with a peaceful game on deity?
