BTW, the titles are hyperlinks.
ModSwapper
Modswapper is the most important download I will list. As it's name suggests it enables the swapping of mod's easily and without overwriting. A must have if you plan on using mods.
Apolyton by
Dale
The Apolyton pack is rare in the sense that it doesn't add any new units to the game. What it does add, however, is many AI and game improvements. More like a patch than a mod, this pack implements many fixes, and is perfect if you don't want to be swamped with new units and buildings. It adds the option of very large maps aswell. Well worth the download if you want to play with the original units.
Cradle by
Hexagonia
Cradle is a mod that focuses on the earlier stages of the game, and it does this
VERY well. It implements new units, ages, buildings, wonders and advances. The start of the game is no longer tedious, and the mod features improvements of the AI through SLIC's like diplomod and Martin's Mods. Other improvements include immortal wombat's disaster SLIC. The AI is great, and can sometimes be a challenge. This mod is fantastic, especially during the earlier times, and is well worth the downloading.
Medieval Mod by
WesW
Medieval Mod adds new units, like cradle, but doesn't limit it's additions to the earlier ages. It features new units, ages, buildings, advances and wonders, along with numerous improvements on the gameplay. It features many improvements in the Modern Age, resulting in a great end to a game around this time. This is a fantastic mod, and is well worth downloading.
Absolute State by
Pedrunn
I have downloaded Absolute State, but I have not yet played it, because I have too many games in progress. It requires the installation of MedMod, and does something about the ages. Not sure exactly, so I am unsure of recommending it, but I am sure that it would be worth the download (~1.5mb).
To Dida
I recommend getting all of the above mods, that is all there is, the other mods found on hexagonia's page are featured in his mod anyway. The order doesn't matter, presumably MedMod must be installed before Absolute State, but other than that, there is only one incompatability between the mods, a minor graphics problem between Cradle and MedMod.
Personal Note
I would like to take the chance to send out a thanks to the following people who have dedicated so much to improve the game:
Hexagonia, WesW, Pedrunn, Dale, Player1, Immortal Wombat, Martin Gühmann, The Guy Who Created Modswapper ???, Peter Triggs, Martin The Dane.
Great work guys
