Warlord
Different difficulty levels for different tastes. If you want an analogy, imagine King got cut off and now the hardest game you can play is Warlord. Would you be happy with such news ?
Thankfully that analogy is hypothetical and therefore will never be the case, so I don't need to worry about such things. I'm actually happy that I'm not good enough to beat the AI on Deity since that would quickly make the game boring (for me at least). Plus, the way you have to play on Deity is very rigid, at least from what I've read and seen. On Deity there are play styles that you MUST follow in order to achieve victory, for me that takes away some of the freedom, which is to me the most important part of playing this game. I don't want to feel locked into any one particular strategy every time I play simply because I need to gain advantages over the extreme bonuses the AI receives.
Besides, it seems like a lot of people here have forgotten that the build Maddjinn is playing in his streams are outdated at this point, possibly by a month or more. Do you really think that Firaxis hasn't made ANY major changes to the AI since that build was published? If so, then yeah, I guess that does suck for Deity players.
At the end of the day though it's all still speculation at this point. We haven't even seen Maddjinn win a game yet; he's come close but so has the AI. I think waiting for someone to start a brand new LP on release day and watching it through is a much better basis for establishing facts about the game, just a suggestion.
