I am really enjoying this mod. The prehistoric age is a gorgeous addition and many other things.
*beams*
I can't take all the credit for the Prehistoric Era since it's based on TheTriturador's Stone Age Mod (which was of sufficient importance for me to include it in the MM title screen), but I significantly redesigned it when making my own version so I feel okay taking about half the credit.
I started on Darkmongoose difficulty. All is nice and hard and I will probably lose (too early to say for sure, still prehistoric and I dont know for sure how ahead they are). Anyway, can I get to know what are the differences between the deity and DM difficulty? I somehow fail to find anything about it with search and ingame pedia.
There's a short blurb about the mod's difficulty levels in the
Stuff to Know sticky thread and included text document, at the top of the "Other Stuff to Know" section.
There are a number of major differences so it's a bit hard to compare them directly. Barbarian densities/quantities are higher in TL and DM than they are in all the standard difficulties. AIs do not gain increasingly stronger advantages in later eras in TL/DM, but their bonuses are set a bit differently; their gold costs for things are higher (generally the same full values human players have to pay), but their growth speeds and building production rates are a little faster and their unit production rates are a lot faster. But, like I said, on the higher standard difficulties AIs get increasing bonuses the later the era they're in, whereas on TL/DM their bonuses are fixed. My current best educated guess is that, averaged out, DarkMongoose is
roughly equivalent to Immortal (assuming you start the game in an early era), so Deity should be harder.
Also, in my previous game I had the nasty palisades building not going obsolete, not staying built and kept annoying me from the building options. maybe you guys know about it but it is creeping me.
This was one of the two major bugs in 3.6 that caused me to do the whole 3.6.1 version sooner than I was planning to. (It was mentioned a half-dozen times here, but I mainly recommend reading over the
Patch Notes in the Download sticky thread's posts or the included text document: it only takes a few minutes, I write them up to be highly organized and readable, and they tell you lots of cool stuff that was added or fixed that you wouldn't even notice otherwise.

Congrats again for all the fun you put into it guys.
There is no "guys"... I'm the sole author. Obviously there's a long Credits section for other people's stuff that was used (and other people's stuff that my stuff was based on), but as far as MM itself goes... yep, just me pretty much. *beams again*
Edit: I partially take my word back, by classical age time between turns is up to 30-40 seconds. I should not have set the raging barbarians on but I thought that they will be the only help I will get against the insane AI. Anyway, it is by far the big mod that runs best on my computer. Btw, I survived this far and in a decent shape. Probably thanks to the huge map and no real proximity to any warmonger AI.
My friend and I always play with Raging Barbs on - much too boring otherwise hehe. They actually don't help at all against strong AIs btw, since AIs get huge combat bonuses vs barbarians (which has always been part of the vanilla difficulty levels so it wasn't something I added). That game option basically gives the AIs more fodder to gain experience from (as well as giving the human players more fodder too). I did actually try removing AI barb bonuses a long time ago, but a few AI players would get completely eliminated by barbarians in the first 200 turns so it didn't seem like a good idea.
Anyway, there is only so much that can be done with a mod, speed-wise. Civ4 is a large, complicated program, and turns always get slower further into a game just b/c there is more going on: more units and cities on the map that need to be processed by the AIs each turn, and more discovered rival players that complicate an AI's thought processes. MM has been as heavily optimized for speed as is possible, and does not run substantially slower than the vanilla, unmodded game as a result (slightly faster in some cases if JDog's figures still hold up). Past a certain point you just need a better computer hehe. Thanks though, appreciate the compliment.
